Commentary on Isaiah 48 verses 16–22
Here, as before, Jacob and Israel are summoned to hearken to the prophet speaking in God's name, or rather to God speaking in and by the prophet, and that as a type of the great prophet by whom God has in these last days spoken unto us, and that is sufficient: Come near therefore, and hear this. Note, Those that would hear and understand what God says must come near, and approach to him; let them come as near as they can. Let those that have hearkened to the tempter now come near, and hear this, that they may be confirmed in their resolutions to serve God. Those that draw nigh to God may depend upon this, that his secret shall be with them. Here,
I. God refers them to what he hath both said to them and done for them formerly, which if they would reflect upon, they might thence fetch great encouragement to trust in God at this time. 1. He had always spoken plainly to them from the beginning, by Moses and all the prophets: I have not spoken in secret, but publicly, from the top of Mount Sinai, and in the chief places of concourse, the solemn assemblies of their tribes; he did not deliver his oracles obscurely and ambiguously, but so that they might be understood, Hab 2:2. 2. He had always acted wonderfully for them: "From the time that they were first formed into a people there I am, there have I been resident among them and presiding in their affairs (he sent them prophets, raised them up judges, and frequently appeared for them), and therefore there I will be still." He that has been with his people hitherto will be to the end.
II. The prophet himself, as a type of the great prophet, asserts his own commission to deliver this message: Now the Lord God (the same that spoke from the beginning and did not speak in secret) has by his Spirit sent me, Isa 48:16. The Spirit of God is here spoken of as a person distinct from the Father and the Son, and having a divine authority to send prophets. Note, Whom God sends the Spirit sends. Those whom God commissions for any service the Spirit in some measure qualifies for it; and those may speak boldly, and must be heard obediently, whom God and his Spirit send. As that which the prophet says to the same purport with this (Isa 61:1) is applied to Christ (Luk 4:21), so may this be; the Lord God sent him, and he had the Spirit without measure.
III. God by the prophet sends them a gracious message for their support and comfort under their affliction. The preface to this message is both awful and encouraging (Isa 48:17): Thus saith Jehovah, the eternal God, thy Redeemer, that has often been so, that has engaged to be so, and will be faithful to the engagement, for he is the Holy One, that cannot deceive, the Holy One of Israel, that will not deceive them. The same words that introduce the law, and give authority to that, introduce the promise, and give validity to that: "I am the Lord thy God, whom thou mayest depend upon as in relation to thee and in covenant with thee."
1.Here is the good work which God undertakes to fulfil in them. He that is their Redeemer, in order to that, will be, (1.) Their instructor: "I am thy God that teaches thee to profit, that is, teaches thee such things as are profitable for thee, things that belong to thy peace." By this God shows himself to be a God in covenant with us, by his teaching us (Heb 8:10, Heb 8:11); and none teaches like him, for he gives an understanding. Whom God redeems he teaches; whom he designs to deliver out of their afflictions he first teaches to profit by their afflictions, makes them partakers of his holiness, for that is the profit for which he chastens us, Heb 12:10. (2.) Their guide: He leads them to the way and in the way by which they should go. He not only enlightens their eyes, but directs their steps. By his grace he leads them in the way of duty, by his providence he leads them in the way of deliverance. Happy are those that are under such a guidance!
2.Here is the good-will which God declares he had for them by his good wishes concerning them, Isa 48:18, Isa 48:19. He had indeed brought them into captivity, but it was owing to themselves, nor did he afflict them willingly. (1.) As when he gave them his law he earnestly wished they might be obedient (O that there were such a heart in them! Deu 5:29. O that they were wise! Deu 32:29), so, when he had punished them for the breach of his law, he wished they had been obedient: O that thou hadst hearkened to my commandments! Isa 48:18. O that my people had hearkened unto me! Psa 81:13. This confirms what God had said and sworn, that he has no pleasure in the death of sinners. (2.) He assures them that, if they had been obedient, that would not only have prevented their captivity, but would have advanced and perpetuated their prosperity. He had abundance of good things ready to bestow upon them if their sins had not turned them away, Isa 59:1, Isa 59:2. [1.] They should have been carried on in a constant uninterrupted stream of prosperity: "Thy peace should have been as a river; thou shouldst have enjoyed a series of mercies, one continually following another, as the waters of a river, which always last." Labitur, et labetur in omne volubilis aevum - It flows, and will for ever flow; not like the waters of a land-flood, which are soon gone. [2.] Their virtue and honour, and the justice of their cause, should in all cases have borne down opposition by their own strength, as the waves of the sea. Such should their righteousness have been that nothing should have stood before it; whereas, now they had been disobedient, the current of their prosperity was interrupted, and their righteousness overpowered. [3.] The rising generation should have been very numerous and very prosperous; whereas they were now very few, as appears by the small number of the returning captives (Ezr 2:64), not so many as of one tribe when they came out of Egypt. They should have been numberless as the sand, according to the promise (Gen 22:17), which they had forfeited the benefit of: "The offspring of thy bowels would have been innumerable, like the gravel of the sea, if thy righteousness had been irresistible and unconquerable as the waves of the sea." [4.] The honour of Israel should still have been unstained, untouched: His name should not have been cut off, as now it is in the land of Israel, which is either desolate or inhabited by strangers; nor should it have been destroyed from before God. We cannot reckon the name either of a family or of a kingdom destroyed till it is destroyed from before God, till it ceases to be a name in his holy place. Now God tells them thus what he would have done for them if they had persevered in their obedience, First, That they might be the more humbled for their sins, by which they had forfeited such rich mercies. Note, This should engage us (I might say, enrage us) against sin, that it has not only deprived us of the good things we have enjoyed, but prevented the good things God had in store for us. It will make the misery of the disobedient the more intolerable to think how happy they might have been. Secondly, That his mercy might appear the more illustrious in working deliverance for them, though they had forfeited it and rendered themselves unworthy of it. Nothing but a prerogative of mercy would have saved them.
3.Here is assurance given of the great work which God designed to work for them, even their salvation out of their captivity, when he had accomplished his work in them.
(1.)Here is a commission granted them to leave Babylon. God proclaimed, long before Cyrus did, that whoever would might return to his own land (Isa 48:20): "You have a full discharge sent you: Go you forth out of Babylon; the prison-doors are thrown open, and the trumpet sounds, proclaiming a release." Perhaps with this word, as a means, the Spirit of the Lord stirred up the spirits of those that did take the benefit of Cyrus's proclamation (Ezr 1:5): Flee you from the Chaldeans, not with an ignominious stolen flight, as Jacob fled from Laban, but with a holy disdain, as scorning to stay any longer among them; flee you, not silently and sorrowfully, but with a voice, with a voice of singing, as they fled of old out of Egypt, Exo 15:1.
(2.)Here is the news of this sent to all parts: "Let it be declared; let it be told; let it be uttered; make it to be heard by the most remote, by the most remiss; send the tidings of it by word of mouth; send it by writing, from city to city, from kingdom to kingdom, even to the utmost regions, to the ends of the earth." This was a figure of the publishing of the gospel to all the world; but that brings glad tidings which all the world is concerned in, this only that which it is fit all should take notice of, that they may be invited by it to forsake their idols and come into the service of the God of Israel. Let them all know then, [1.] That those whom God owns for his are such as he has dearly bought and paid for: The Lord has redeemed his servant Jacob; he has done it formerly, when he brought them out of Egypt, and now he is about to do it again. Jacob was God's servant, and therefore he redeemed him; for what had other masters to do with God's servants? Israel is God's son, therefore Pharaoh must let him go. God redeemed Jacob, and therefore it was fit that he should be his servant (Psa 116:16); the bonds God had loosed tied them the faster to him. He that redeemed us has an unquestionable right to us. [2.] That those whom God designs to bring home to himself he will take care of, that they want not for the necessary expenses of their journey. When he brought them out of Egypt, and led them through the deserts, they thirsted not (Isa 48:21), for in all their removals the water out of the rock followed them; thence he caused the waters to flow, and, since rock-water is the clearest and finest, God clave the rock, and the waters gushed out; for he can fetch in necessary supplies for his people in a way that they think the least likely. This refers to what he did for them when he brought them out of Egypt; when all this was literally true. But it should now be in effect done again, in their return out of Babylon, so well provided for should they and theirs be in their return. God does his work as effectually by marvellous providences as by miracles, though perhaps they are not so much taken notice of. This is applicable to those treasures of grace laid up for us in Jesus Christ, from which all good flows to us as the water did to Israel out of the rock, for that rock is Christ.
(3.)Here is a caveat put in against the wicked who go on still in their trespasses. Let not them think to have any benefit among God's people. Though in show and profession they herd themselves among them, let them not expect to come in sharers; no (Isa 48:22), though God's thoughts concerning the body of that people were thoughts of peace, yet to those among them that were wicked and hated to be reformed there is no peace, no peace with God or their own consciences, no real good, whatever is pretended to. What have those to do with peace who are enemies to God? Their false prophets cried Peace to those to whom it did not belong; but God tells them that there shall be no peace, nor any think like it, to the wicked. The quarrel sinners have commenced with God, if not taken up in time by repentance, will be an everlasting quarrel.
(Verse 20, 21, 22.) Go out of Babylon, flee from the Chaldeans; proclaim it with a shout of joy, make it heard, proclaim it to the ends of the earth, and say: The Lord has redeemed his servant Jacob. They did not thirst when he led them through the desert; he made water flow for them from the rock; he split the rock and water gushed out. There is no peace for the wicked, says the Lord. Those above in that place, where it is written: I have spoken and called it; I have brought him and his way is straight; they understand it concerning Cyrus and Darius; even this refers to those times when the people went out of Babylon and fled from the Chaldeans, and they were redeemed by their Lord God. This also, which is said: They did not thirst in the desert when he led them out, he brought water from the rock for them; and he split the rock, and water flowed. Although they cannot teach that it was fulfilled according to history; for they did not come through the desert under Zerubbabel and Ezra, and the split rock provided them water, as is narrated to have happened to those coming out of Egypt: however, they testify hyperbolically that it was fulfilled in likeness to the previous happiness, when they came through the desert of nations into Judaea, and were liberated from captivity. And so, they say, it is not about Christ, but about Cyrus that it is prophesied: There is no peace for the wicked, says the Lord. And it is understood to mean that perfect happiness will not exist except under Christ, which is reserved for the last time. Moreover, those who interpret this more truly and rightly refer it to the coming of the Savior, of whom it is said: He has sent me to announce good news to the poor, to proclaim freedom for prisoners. They understand it as an exhortation for those who proclaim the Gospel of the Lord Savior himself, so that we may come out of Babylon, that is, the confusion of this world, and flee from the Chaldeans, of whom it is often said: For the Lord has redeemed his servant Jacob with his precious blood and led him through the desert of the world and split the rock to give water. The Apostle speaks excellently: But the rock was Christ (I Cor. X, 4). However, the divine word is divided and divided into many parts, so that we may receive it in parts, since we cannot receive it all at once. And so that it may not be thought that this preaching is directed to all the descendants of Jacob and not only to those who will believe through the Apostles, it is added and connected: There is no peace for the wicked, says the Lord, namely those who have remained in their original error; those who do not deserve to drink from the rock. Whose side pierced with a spear, flowed with water and blood (John 19), giving us baptism and martyrdom.
The three interpreters treat this as if it were something that had already occurred: “You made water flow for them from a rock; the waters broke the hard rock and flowed out.” According to the Septuagint, the text alludes to the prophetic grace the Jews enjoyed drinking in divine draughts even while in Babylon from the prophets Daniel and Ezekiel. Because they found themselves in a desert of sorts as a result of the impiety of the Babylonians, they possessed a kind of rock in the prophecy that poured for them the drink of salvation. Further, even after the return from exile, it was Haggai, Zechariah and Malachi who presented to them these divine waters, while the admirable Zerubbabel and the high priest Joshua, the son of Jozadek, wore their piety like a necklace. They offered divine teaching to them like water to the thirsty.

SUMMARY
Isaiah 48:21 stands as a powerful testament to God's unwavering faithfulness and miraculous provision for His people during their Exodus journey through the wilderness. This verse, strategically placed within a broader prophetic discourse of comfort and deliverance for the exiles in Babylon, serves as a divine assurance that the same God who sustained Israel in the most desolate conditions will surely provide for and lead them through their current and future trials, particularly their impending return from captivity. It is a profound reminder of divine sustenance in the face of seemingly impossible circumstances, underscoring God's omnipotent care for His covenant people.
CONTEXT
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
Isaiah 48:21 is rich with literary devices that amplify its message of divine power and provision. The most prominent is Allusion, directly referencing the historical events of the Exodus, specifically the provision of water from the rock as recorded in Exodus 17:6 and Numbers 20:11. This allusion serves to remind the exiles of God's past faithfulness and miraculous power, thereby building confidence for His future deliverance. The use of Hyperbole is subtly present in "thirsted not," which, while literally true due to God's provision, emphasizes the complete eradication of a life-threatening need, implying not just sufficiency but an abundance that defied the natural conditions of a desert. The vivid verbs "clave" and "gushed out" create powerful Imagery, allowing the reader to visualize the dramatic splitting of the rock and the abundant, forceful flow of water, emphasizing the extraordinary nature of the miracle. This imagery also contributes to a strong sense of Divine Action, with God consistently presented as the active subject of every verb ("he led," "he caused," "he clave"), underscoring His direct, powerful, and personal intervention. Furthermore, the passage employs a form of Parallelism by reiterating the action of "claving the rock" and the result of water flowing, reinforcing the certainty and completeness of God's provision and His unwavering commitment to His people.
THEOLOGICAL AND THEMATIC CONNECTIONS
Isaiah 48:21 is a profound theological statement wrapped in historical recollection, serving as a powerful anchor for the exiles' hope. It asserts God's unwavering faithfulness (Hesed) to His covenant people, even when they have been disobedient and are facing the consequences of their sin. The miracle of water from the rock demonstrates God's absolute sovereignty over creation and His intimate, compassionate concern for the physical well-being of His people. This historical act serves as a powerful paradigm for future deliverance, particularly for the exiles in Babylon. Just as God miraculously sustained Israel in the literal desert, He promises to sustain them through the "desert" of exile and lead them back to their land. It underscores the theme of God as the ultimate Provider, capable of meeting needs in the most impossible circumstances, and reinforces the truth that His power is not diminished by time or human failure. This divine provision is not merely an act of power but an expression of His covenant love and commitment to His chosen nation, ensuring their survival and the continuation of His redemptive plan for all humanity.
REFLECTION AND APPLICATION
For believers today, Isaiah 48:21 stands as an enduring testament to God's unchanging character as a faithful and powerful Provider. Life often presents its own "deserts"—periods of spiritual dryness, financial hardship, emotional distress, relational brokenness, or overwhelming uncertainty. In these desolate seasons, this verse reminds us that God is not limited by our circumstances or the apparent impossibility of our situations. Just as He caused water to gush from a solid rock, He can bring forth provision, comfort, and hope from seemingly barren and impossible situations. It calls us to trust in His sovereign leading, even when the path is unclear or fraught with challenges, recognizing that His presence transforms the wilderness into a place of provision. Our responsibility is not to generate the water, but to follow the One who leads us and provides it. This passage encourages us to look back at God's past faithfulness in our own lives and in the grand narrative of His people, drawing confidence that the God who has provided before will continue to provide, often in unexpected and miraculous ways, ensuring that we "thirst not" for what truly matters for our journey of faith.
Questions for Reflection
FAQ
Why does Isaiah recall the Exodus event here, centuries after it occurred?
Answer: Isaiah recalls the Exodus event in Isaiah 48:21 primarily for two strategic reasons, both aimed at the exiles in Babylon. First, it serves as an undeniable historical proof of God's power and faithfulness. For a people feeling abandoned and questioning God's ability to save, recalling such a foundational miracle reminded them that their God is truly sovereign over nature and history, unlike the impotent idols of Babylon. Second, and crucially, it functions as a powerful paradigm for the "new Exodus" that God is promising to bring about—their return from Babylonian captivity. Just as He miraculously led and sustained their ancestors through the literal desert, He promises to do the same for them in their return journey, making a way in the wilderness and providing for their needs, as powerfully prophesied in Isaiah 43:19-20. It grounds future hope in past, undeniable divine action.
What is the theological significance of water from the rock?
Answer: Theologically, water from the rock signifies God's life-sustaining provision and His ever-present faithfulness with His people. In the barren wilderness, water was not merely a convenience but essential for survival, making its miraculous appearance a direct demonstration of God's intimate care for their physical needs. Beyond physical sustenance, the rock itself became a profound symbol of God's steadfastness and a source of spiritual life. The Apostle Paul later provides a profound New Testament interpretation, stating in 1 Corinthians 10:4 that the rock from which they drank "was Christ." This elevates the historical event to a typological level, foreshadowing Jesus as the ultimate source of living water and spiritual nourishment for all who believe.
How does this verse relate to God's promises for the future?
Answer: Isaiah 48:21 is deeply intertwined with God's promises for the future, particularly for the exiles in Babylon. By recalling His past miraculous provision, God establishes an irrefutable basis of trust for His future actions. He is essentially saying, "The God who did this for your ancestors in the wilderness is the same God who will now lead you out of Babylon and sustain you on your journey home." This verse assures them that their God is not absent or powerless, but actively involved in their deliverance and committed to their well-being. It provides a historical anchor for the prophetic promises of a new era of salvation, where God will once again demonstrate His power and faithfulness to His people, fulfilling His covenant promises and bringing them to a place of rest and blessing.
CHRIST-CENTERED FULFILLMENT
Isaiah 48:21, though rooted in Old Testament history and God's miraculous provision for Israel in the wilderness, finds its ultimate and most profound fulfillment in the person and work of Jesus Christ. The Apostle Paul's powerful declaration in 1 Corinthians 10:4 that "the Rock was Christ" transforms the historical event into a profound type, revealing Christ as the eternal, inexhaustible source of life-giving provision. Just as the physical rock in the wilderness provided water to sustain Israel's physical lives, Jesus is the spiritual Rock who provides the living water that quenches the deepest spiritual thirst of humanity. He Himself proclaimed, "If anyone thirsts, let him come to me and drink" (John 7:37), and promised that those who drink of the water He gives will "never be thirsty again" (John 4:14). The miraculous gushing forth of water from the smitten rock foreshadows Christ's own sacrifice on the cross, where His side was pierced, and from Him flowed the life-giving Spirit and grace for all who believe (John 19:34). Thus, Isaiah 48:21 points beyond mere physical sustenance to the spiritual sustenance found exclusively in Christ, who not only leads us through the deserts of this life but is Himself the inexhaustible spring of eternal life and divine provision, ensuring that all who come to Him will never truly thirst.
