Commentary on Psalms 81 verses 8–16
God, by the psalmist, here speaks to Israel, and in them to us, on whom the ends of the world are come.
I. He demands their diligent and serious attention to what he was about to say (Psa 81:8): "Hear, O my people! and who should hear me if my people will not? I have heard and answered thee; now wilt thou hear me? Hear what is said with the greatest solemnity and the most unquestionable certainty, for it is what I will testify unto thee. Do not only give me the hearing, but hearken unto me, that is, be advised by me, be ruled by me." Nothing could be more reasonably nor more justly expected, and yet God puts an if upon it: "If thou wilt hearken unto me. It is thy interest to do so, and yet it is questionable whether thou wilt or no; for thy neck is an iron sinew."
II. He puts them in mind of their obligation to him as the Lord their God and Redeemer (Psa 81:10): I am the Lord thy God, who brought thee out of the land of Egypt; this is the preface to the ten commandments, and a powerful reason for the keeping of them, showing that we are bound to it in duty, interest, and gratitude, all which bonds we break asunder if we be disobedient.
III. He gives them an abstract both of the precepts and of the promises which he gave them, as the Lord and their God, upon their coming out of Egypt. 1. The great command was that they should have no other gods before him (Psa 81:9): There shall no strange god be in thee, none besides thy own God. Other gods might well be called strange gods, for it was very strange that ever any people who had the true and living God for their God should hanker after any other. God is jealous in this matter, for he will not suffer his glory to be given to another; and therefore in this matter they must be circumspect, Exo 23:13. 2. The great promise was that God himself, as a God all-sufficient, would be nigh unto them in all that which they called upon him for (Deu 4:7), that, if they would adhere to him as their powerful protector and ruler, they should always find him their bountiful benefactor: "Open thy mouth wide and I will fill it, as the young ravens that cry open their mouths wide and the old ones fill them." See here, (1.) What is our duty - to raise our expectations from God and enlarge our desires towards him. We cannot look for too little from the creature nor too much from the Creator. We are not straitened in him; why therefore should we be straitened in our own bosoms? (2.) What is God's promise. I will fill thy mouth with good things, Psa 103:5. There is enough in God to fill our treasures (Pro 8:21), to replenish every hungry soul (Jer 31:25), to supply all our wants, to answer all our desires, and to make us completely happy. The pleasures of sense will surfeit and never satisfy (Isa 55:2); divine pleasures will satisfy and never surfeit. And we may have enough from God if we pray for it in faith. Ask, and it shall be given you. He gives liberally, and upbraids not. God assured his people Israel that it would be their own fault if he did not do as great and kind things for them as he had done for their fathers. Nothing should be thought too good, too much, to give them, if they would but keep close to God. He would moreover have given them such and such things, Sa2 12:8.
IV. He charges them with a high contempt of his authority as their lawgiver and his grace and favour as their benefactor, Psa 81:11. He had done much for them, and designed to do more; but all in vain: "My people would not hearken to my voice, but turned a deaf ear to all I said." Two things he complains of: - 1. Their disobedience to his commands. They did hear his voice, so as never any people did; but they would not hearken to it, they would not be ruled by it, neither by the law nor by the reason of it. 2. Their dislike of his covenant-relation to them: They would none of me. They acquiesced not in my word (so the Chaldee); God was willing to be to them a God, but they were not willing to be to him a people; they did not like his terms. "I would have gathered them, but they would not." They had none of him; and why had they not? It was not because they might not; they were fairly invited into covenant with God. It was not because they could not; for the word was nigh them, even in their mouth and in their heart. But it was purely because they would not. God calls them hi people, for they were bought by him, bound to him, his by a thousand ties, and yet even they had not hearkened, had not obeyed. "Israel, the seed of Jacob my friend, set me at nought, and would have none of me." Note, All the wickedness of the wicked world is owing to the wilfulness of the wicked will. The reason why people are not religious is because they will not be so.
V. He justifies himself with this in the spiritual judgments he had brought upon them (Psa 81:12): So I gave them up unto their own hearts' lusts, which would be more dangerous enemies and more mischievous oppressors to them than any of the neighbouring nations ever were. God withdrew his Spirit from them, took off the bridle of restraining grace, left them to themselves, and justly; they will do as they will, and therefore let them do as they will. Ephraim is joined to idols; let him alone. It is a righteous thing with God to give those up to their own hearts' lusts that indulge them, and give up themselves to be led by them; for why should his Spirit always strive? His grace is his own, and he is debtor to no man, and yet, as he never gave his grace to any that could say they deserved it, so he never took it away from any but such as had first forfeited it: They would none of me, so I gave them up; let them take their course. And see what follows: They walked in their own counsels, in the way of their heart and in the sight of their eye, both in their worships and in their conversations. "I left them to do as they would, and then they did all that was ill;" they walked in their own counsels, and not according to the counsels of God and his advice. God therefore was not the author of their sin; he left them to the lusts of their own hearts and the counsels of their own heads; if they do not well, the blame must lie upon their own hearts and the blood upon their own heads.
VI. He testifies his good-will to them in wishing they had done well for themselves. He saw how sad their case was, and how sure their ruin, when they were delivered up to their own lusts; that is worse than being given up to Satan, which may be in order to reformation (Ti1 1:20) and to salvation (Co1 5:5); but to be delivered up to their own hearts' lusts is to be sealed under condemnation. He that is filthy, let him be filthy still. What fatal precipices will not these hurry a man to! Now here God looks upon them with pity, and shows that it was with reluctance that he thus abandoned them to their folly and fate. How shall I give thee up, Ephraim? Hos 11:8, Hos 11:9. So here, O that my people had hearkened! See Isa 48:18. Thus Christ lamented the obstinacy of Jerusalem. If thou hadst known, Luk 19:42. The expressions here are very affecting (Psa 81:13-16), designed to show how unwilling God is that any should perish and desirous that all should come to repentance (he delights not in the ruin of sinful persons or nations), and also what enemies sinners are to themselves and what an aggravation it will be of their misery that they might have been happy upon such easy terms. Observe here,
1.The great mercy God had in store for his people, and which he would have wrought for them if they had been obedient. (1.) He would have given them victory over their enemies and would soon have completed the reduction of them. They should not only have kept their ground, but have gained their point, against the remaining Canaanites, and their encroaching vexatious neighbours (Psa 81:14): I should have subdued their enemies; and it is God only that is to be depended on for the subduing of our enemies. Not would had have put them to the expense and fatigue of a tedious war: he would soon have done it; for he would have turned his hand against their adversaries, and then they would not have been able to stand before them. It intimates how easily he would have done it and without any difficulty. With the turn of a hand, nay, with the breath of his mouth, shall he slay the wicked, Isa 11:4. If he but turn his hand, the haters of the Lord will submit themselves to him (Psa 81:15); and, though they are not brought to love him, yet they shall be made to fear him and to confess that he is too hard for them and that it is in vain to contend with him. God is honoured, and so is his Israel, by the submission of those that have been in rebellion against them, though it be but a forced and feigned submission. (2.) He would have confirmed and perpetuated their posterity, and established it upon sure and lasting foundations. In spite of all the attempts of their enemies against them, their time should have endured for ever, and they should never have been disturbed in the possession of the good land God had given them, much less evicted and turned out of possession. (3.) He would have given them great plenty of all good things (Psa 81:16): He should have fed them with the finest of the wheat, with the best grain and the best of the kind. Wheat was the staple commodity of Canaan, and they exported a great deal of it, Eze 27:17. He would not only have provided for them the best sort of bread, but with honey out of the rock would he have satisfied them. Besides the precious products of the fruitful soil, that there might not be a barren spot in all their land, even the clefts of the rock should serve for bee-hives and in them they should find honey in abundance. See Deu 32:13, Deu 32:14. In short, God designed to make them every way easy and happy.
2.The duty God required from them as the condition of all this mercy. He expected no more than that they should hearken to him, as a scholar to his teacher, to receive his instructions - as a servant to his master, to receive his commands; and that they should walk in his ways, those ways of the Lord which are right and pleasant, that they should observe the institutions of his ordinances and attend the intimations of his providence. There was nothing unreasonable in this.
3.Observe how the reason of the withholding of the mercy is laid in their neglect of the duty: If they had hearkened to me, I would soon have subdued their enemies. National sin or disobedience is the great and only thing that retards and obstructs national deliverance. When I would have healed Israel, and set every thing to-rights among them, then the iniquity of Ephraim was discovered, and so a stop was put to the cure, Hos 7:1. We are apt to say, "If such a method had been taken, such an instrument employed, we should soon have subdued our enemies:" but we mistake; if we had hearkened to God, and kept to our duty, the thing would have been done, but it is sin that makes our troubles long and salvation slow. And this is that which God himself complains of, and wishes it had been otherwise. Note, Therefore God would have us do our duty to him, that we may be qualified to receive favour from him. He delights in our serving him, not because he is the better for it, but because we shall be.
I would therefore beseech you, Pammachius, as a foremost lover of learning, and Marcella, as an outstanding examplar of Roman virtue, men who are bound together by faith and blood, to lend aid to my efforts by your prayers, in order that our Lord and Savior might in His own cause and by His mind make answer through my mouth. For it is He who says to the prophet, "Open thy mouth and I will fill it" (Psalm 81:10). For if He admonishes us, when we have been hailed before judges and tribunals, not to ponder what answer we are to give to them (Luke 12:11-12), how much more is He able to carry on His own war against blaspheming adversaries and through His servants to vanquish them?
For if there be error in you, You will not worship a strange god. If you think not of a false god, you will not worship a manufactured god: for "there will not" be in you any strange god. "For I am." Why would you adore what is not? "For I am the Lord your God" [Psalm 81:10]. Because "I am I that Am," and indeed "I Am" He says, I that Am, over every creature: yet to you what good have I afforded in time? "Who brought you out of the land of Egypt." Not to that people alone is it said. For we all were brought out of the land of Egypt, we have all passed through the Red Sea; our enemies pursuing us have perished in the water. Let us not be ungrateful to our God; let us not forget God that abides, and fabricate in ourselves a new god. "I, who led you out of the land of Egypt," says God. "Open wide your mouth, and I will fill it." You suffer straitness in yourself because of the new god set up in your heart; break the vain image, cast down from your conscience the feigned idol: "open wide your mouth," in confessing, in loving: "and I will fill it," because with me is the fountain of life.
And indeed I do not see that I am sufficient for this work; but nevertheless the strength that inexperience denies, charity supplies. For I know Him who said: "Open your mouth, and I will fill it." Therefore let the good work be in our will, for from divine assistance it will be in its completion.

SUMMARY
Psalms 81:10 presents a profound declaration of God's covenantal identity and His boundless capacity to provide for His people, contingent upon their faithful obedience. It serves as a powerful reminder of Yahweh's past redemptive acts, particularly the Exodus, and extends an open invitation to experience His abundant, satisfying provision for all needs—spiritual, physical, and emotional—if they will but trust Him fully and express their needs expansively.
CONTEXT
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
The verse employs several potent Literary Devices. The most prominent is Metaphor, specifically in the phrase "open thy mouth wide, and I will fill it." This vivid image transforms the abstract concept of spiritual hunger and divine provision into a concrete, relatable act, akin to a hungry bird opening its beak for food. This Anthropomorphism (attributing human-like actions to God, in His promise to "fill" the mouth) underscores His personal engagement and responsiveness to His people's needs. The structure of the verse also demonstrates Parallelism and Cause-and-Effect, where God's identity and past actions ("I am the LORD... which brought thee out...") serve as the basis for His present command and future promise ("open thy mouth wide, and I will fill it"). This establishes a logical and theological connection between His nature, His history, and His ongoing desire to bless. The declaration "I am the LORD thy God" also functions as a powerful Assertion of Authority, setting the tone for the divine oracle that follows.
THEOLOGICAL AND THEMATIC CONNECTIONS
Psalms 81:10 beautifully encapsulates the essence of God's covenant relationship with His people: He is the faithful Deliverer who invites radical trust and promises abundant provision. This verse echoes the foundational truth that God's identity as "Yahweh" is inextricably linked to His redemptive acts and His commitment to His covenant. The invitation to "open thy mouth wide" is a call to expansive faith, recognizing that God's capacity to give far exceeds human limitations or expectations. It challenges believers to move beyond meager requests, trusting in a God whose resources are infinite and whose desire is to satisfy deeply and completely. This principle of asking boldly and receiving abundantly is a recurring theme throughout Scripture, highlighting God's generosity and His desire for His people to live in fullness.
REFLECTION AND APPLICATION
Psalms 81:10 serves as a timeless invitation for believers today to engage with God in a posture of profound trust and expansive expectation. Just as God delivered Israel from physical bondage, He has delivered us from spiritual slavery through Christ. This verse prompts us to reflect on God's past faithfulness in our own lives, remembering His consistent provision and deliverance, which then strengthens our faith for present and future challenges. The call to "open thy mouth wide" challenges the often-limited scope of our prayers and desires. Are we truly bringing our deepest needs, our largest aspirations, and our most audacious requests before the Lord, or are we constrained by our own perceived limitations, past disappointments, or a small view of God? God desires to fill us not only with physical sustenance but with spiritual nourishment, wisdom, peace, strength, and the very presence of His Spirit. He invites us to approach Him with a boundless confidence, knowing that His capacity to give is infinite and His desire to bless is unwavering, leading to a life of true flourishing.
Questions for Reflection
FAQ
Does "open thy mouth wide" refer only to physical needs, or does it have a broader meaning?
Answer: While the imagery of "filling" can certainly include physical sustenance, the context and broader biblical themes suggest a much wider application. "Open thy mouth wide" primarily refers to expressing a deep, expansive spiritual hunger, an unreserved readiness to receive from God in all aspects of life—spiritual wisdom, peace, joy, strength, guidance, and even physical provision. It encompasses a posture of complete dependence and expectant faith for all that God desires to pour into His people's lives for their well-being and flourishing. This is consistent with how Jesus taught about seeking the kingdom of God first, with all other things being added to those who prioritize His reign.
Is God's promise to "fill it" conditional on my obedience?
Answer: The immediate literary context of Psalm 81 (vv. 11-16) strongly suggests that while God's desire to fill is boundless, the experience of that abundant filling is indeed conditional on Israel's willingness to listen and obey His voice. God laments that Israel "would not hearken to my voice" (v. 11), leading to a forfeiture of the blessings He longed to bestow. Therefore, while God's character and capacity to provide are unchanging, our receptivity to His blessings is often tied to our posture of trust, obedience, and alignment with His will. This aligns with the New Testament teaching that obedience is a fruit of faith, and that those who abide in Christ and His words can ask what they desire and it will be done, because their desires are aligned with His.
CHRIST-CENTERED FULFILLMENT
Psalms 81:10 finds its ultimate and most profound fulfillment in Jesus Christ. The "LORD thy God, which brought thee out of the land of Egypt" foreshadows Christ, who delivers humanity from a far greater bondage—the slavery of sin and death. Just as the Exodus was the foundational act of Israel's redemption, Christ's death and resurrection constitute the definitive act of spiritual liberation for all who believe (Colossians 1:13-14). The invitation to "open thy mouth wide, and I will fill it" is gloriously realized in Christ, who declared Himself the "bread of life" (John 6:35) and the source of "living water" (John 4:14). Through Him, believers are invited to come boldly to the throne of grace, where they can receive abundant grace and mercy to help in time of need (Hebrews 4:16). The "filling" promised by God is now experienced through the indwelling Holy Spirit, who empowers, guides, and satisfies the deepest spiritual hungers of those who trust in Christ (Ephesians 5:18). In Christ, God's boundless provision is not merely a promise for a nation, but a personal reality for every believer, enabling them to live a life of fullness and abundance (John 10:10).
