Commentary

Hosea 14:9

Who is wise, and he shall understand these things? prudent, and he shall know them? for the ways of the LORD are right, and the just shall walk in them: but the transgressors shall fall therein.

And to such a degree does the gospel desire that there should be wise people among believers, that for the sake of exercising the understanding of its hearers, it has spoken certain truths in enigmas, others in what are called “dark” sayings, others in parables, and others in problems. And one of the prophets—Hosea—says at the end of his prophecy, “Who is wise, and he will understand these things? Or prudent, and he shall know them?”
Isaiah 1:2

Hear, O heavens, and give ear, O earth: for the LORD hath spoken, I have nourished and brought up children, and they have rebelled against me.

All that exists was created by God, and there is nothing uncreated except the nature of the Father, Son and Holy Spirit. God, who is good by nature, wishing to have those whom he might benefit and who might enjoy the benefits received from him, made creatures worthy of himself, that is, who could receive him worthily.
Isaiah 1:3

The ox knoweth his owner, and the ass his master's crib: but Israel doth not know, my people doth not consider.

That manger was the one the prophet meant when he said, “The ox knows his owner and the donkey his master’s manger.” The ox is a clean animal, and the donkey an unclean one.… The people of Israel did not know the manger of their Lord, but the unclean Gentiles did.… We should strive to recognize the Lord and to be worthy of knowing him. We should strive to appropriate not only his birth and fleshly resurrection but also his anticipated second coming in majesty.
Isaiah 1:6 · 2 passages

From the sole of the foot even unto the head there is no soundness in it; but wounds, and bruises, and putrifying sores: they have not been closed, neither bound up, neither mollified with ointment.

And just as there are some wounds that are cured by emollients, others that are cured by oil and others that need a bandage, there are still other wounds about which it is said, “It is not emollients or oil or bandages; but your land is desolate, your cities burned with fire.” So there are some sins that pollute the soul, and for those sins one needs the lye of the Word, the soap of the Word. Yet some sins are not cured this way, because they do not pollute the soul.
Isaiah teaches that there are certain wounds of the soul.… Without doubt, he is speaking about the transgressions of the people, because there are some to whom the medicine of the poultice must still be applied. Others may be sinners in such a degree that no cure can be found for them.
Isaiah 1:7-8

Your country is desolate, your cities are burned with fire: your land, strangers devour it in your presence, and it is desolate, as overthrown by strangers.

Christ ceased to be in them. The Word deserted them.… The Jews were left behind, and salvation passed to the Gentiles. God meant to spur on the Jews with envy. We contemplate God’s mysterious plan, how for our salvation he rejected Israel. We ought to be careful. The Jews were rejected for our sake; on our account they were abandoned. We would deserve even greater punishment if we did nothing worthy of our adoption by God and of his mercy. In his mercy God adopted us and made us his sons [children] in Christ Jesus, to whom is glory and power for ages of ages.
Isaiah 1:13

Bring no more vain oblations; incense is an abomination unto me; the new moons and sabbaths, the calling of assemblies, I cannot away with; it is iniquity, even the solemn meeting.

Tell me, you who come to church only on festal days, are the other days not festal days? Are they not the Lord’s days? It belongs to the Jews to observe religious ceremonies on fixed and infrequent days.… God hates, therefore, those who think that the festal day of the Lord is on one day.
Isaiah 2:8

Their land also is full of idols; they worship the work of their own hands, that which their own fingers have made:

Not only do human beings "make gods for themselves" from statues, but you will also find them "making gods for themselves" from their imaginations. For such people can imagine another god and creator of the world in a system different from the divine plan of the world recorded by the Spirit, other than the true world. These all have "made gods for themselves," and they have "worshiped the works of their hands." So, too, I believe is the case either among the Greeks who generate opinions, so to speak, of this philosophy or that, or among the heretics, the first who generate opinions. These have "made idols for themselves" and figments of the soul, and by turning to them "they worship the works of their hands," since they accept as truth their own fabrications.
Isaiah 4:4 · 2 passages

When the Lord shall have washed away the filth of the daughters of Zion, and shall have purged the blood of Jerusalem from the midst thereof by the spirit of judgment, and by the spirit of burning.

When one has recognized the differences in sins, one can see how the Lord says in Isaiah, "The Lord will wash away the filth of the sons and daughters of Zion and will cleanse the blood from their midst by a spirit of judgment and a spirit of burning." Filth is washed away by a spirit of judgment. Blood is washed away by a spirit of burning. Even if you have not committed a sin that leads to death, you have still sinned and have thereby become filthy. The Lord will wash away the filth of the sons and daughters of Zion, and he will cleanse the blood from among them. A spirit of judgment will be the recompense for filth, and a spirit of burning will be a recompense for the blood. Whenever we commit heinous sins, we do not need lye or washing with soap; rather we need the spirit of burning.
Then the gospel says, "When the days of their purification were fulfilled, according to the law of Moses, they brought him into Jerusalem." The passage says, on account of "their" purification. Who are "they"? If Scripture had said, "on account of 'her' purification"—that is, Mary's, who had given birth—then no question would arise. We would say confidently that Mary, who was a human being, needed purification after childbirth. But the passage reads, "the days of their purification." Apparently it does not signify one but two or more. Did Jesus therefore need purification? Was he unclean or polluted with some stain? Perhaps I seem to speak rashly; but the authority of Scripture prompts me to ask. See what is written in the book of Job: "No man is clean of stain, not even if his life had lasted but a single day." The passage does not say, "No man is clean of sin," but "No man is clean of stain." "Stain" and "sins" do not mean the same thing. "Stain" is one thing, "sin" another. Isaiah teaches this clearly when he says, "The Lord will wash away the stains of the sons and daughters of Z…

By the spirit of judgment he will purge the stain, and by the spirit of burning the blood."Every soul that has been clothed with a human body has its own "stain." But Jesus was stained through his own will, because he had taken on a human body for our salvation.
Isaiah 5:4-6

What could have been done more to my vineyard, that I have not done in it? wherefore, when I looked that it should bring forth grapes, brought it forth wild grapes?

See then how very bad sinning is, that they may be delivered to Satan, who holds captive the souls of those forsaken by God—though God does not forsake without cause or judgment those whom he has abandoned. For when he sends the rain for the vineyard and the vineyard bears thorns instead of grapes, what else will God do except order the clouds not to sprinkle rain on the vineyard?
Isaiah 6:3 · 2 passages

And one cried unto another, and said, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.

My Hebrew teacher also used to teach as follows, that since the beginning or the end of all things could not be comprehended by any except our Lord Jesus Christ and the Holy Spirit, this was the reason why Isaiah spoke of there being in the vision that appeared to him two seraphim only, who with two wings cover the face of God, with two cover his feet and with two fly, crying one to another and saying, “Holy, holy, holy is the Lord of hosts; the whole earth is full of your glory.” For because the two seraphim alone have their wings over the face of God and over his feet, we may venture to declare that neither the armies of the holy angels, nor the holy thrones, nor the dominions, nor principalities nor powers can wholly know the beginnings of all things and the ends of the universe.
My Hebrew master used to say that the two seraphim, which are described in Isaiah as having six wings each and as crying one to another and saying, “Holy, holy, holy is the Lord of hosts,” were to be understood to mean the only-begotten Son of God and the Holy Spirit.
Isaiah 6:7

And he laid it upon my mouth, and said, Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged.

We read also in Isaiah that the prophet is purified with fire by “one of the seraphim which was sent to him, when he took with a pair of tongs one coal from those which were upon the altar; and he touched the lips of the prophet and said, Behold, I have taken away your iniquities.” These appear to me to be mystical and to indicate that the coals are put on the members of each in proportion to his sins, if he is worthy to be purified. For since the prophet says here, “I have unclean lips; also I dwell in the midst of a people who have unclean lips.” For this reason, “a coal taken up with a pair of tongs” by the seraphim cleanses his lips.… The cleansing of his lips indicates that Isaiah’s sin continually would be found only in words, but he would not have sinned in any act or deed. Otherwise, he would have said since I have an unclean body or I have unclean eyes, if he had sinned in desiring what belongs to something other than his lips. He would have said I have unclean hands, if he had polluted these with unjust deeds. But now since possibly he was aware of his transgression in word…

But now since possibly he was aware of his transgression in word alone, about which the Lord says, “Likewise, you will give an account for every useless word on the day of judgment”; because it is difficult even for the perfect to escape the fault of the word, the prophet was likewise in need only of a purification of his lips.
Isaiah 8:9

Associate yourselves, O ye people, and ye shall be broken in pieces; and give ear, all ye of far countries: gird yourselves, and ye shall be broken in pieces; gird yourselves, and ye shall be broken in pieces.

And what the same prophet said has been fulfilled. “God is with us. Know this, O nations, and be conquered.” For we who are from the nations have been conquered and overcome. And we who bend our necks beneath his grace stand forth as a kind of spoils of his victory.
Isaiah 9:2

The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined.

Now the expression darkness will likewise be used to refer to two corresponding concepts. The statement “And God called the light day, and the darkness he called night” is an example of the more common meaning. An example of the spiritual meaning occurs in the statement “The people who sat in darkness … and in the shadow of death, light has dawned on them.”
Isaiah 10:10-11

As my hand hath found the kingdoms of the idols, and whose graven images did excel them of Jerusalem and of Samaria;

Unquestionably, at the time when the early Israelites fell into sin, religion languished. Judah made for themselves "statues in Jerusalem," as well as in that part that came to be called Israel, "in Samaria." But even now, if one considers the mass of sinners taken together, it would not be hard to say that everyone who, serving sin, makes a god out of what seems good to him—making a statue, casting the work of an artisan, setting it up in secret—is under the curse. It is precisely in the secret of the heart that we fabricate many idols when we sin. Therefore the Word admonishes us to do penance and to "cry out in lamentation over the statues" and the idols that are "in Jerusalem and in Samaria." Truly, if we who desire to be of the church commit sin, we fabricate "statues in Jerusalem." If those who are outside of the church sin, as heretics, they make "idols in Samaria." Nevertheless God, in conformity with his goodness, calls all to repentance, saying, "Cry out in lamentation, statues, in Jerusalem and in Samaria, since as I have acted toward Samaria and the works of their hands…

The threat will be carried out toward those who are in the church just as it was with the Samaritans.

HOMILIES ON ISAIAH 8:1

Isaiah 14:4

That thou shalt take up this proverb against the king of Babylon, and say, How hath the oppressor ceased! the golden city ceased!

According to Isaiah, in which lament is offered on behalf of the king of Babylon, much can be learned about the origin and beginning of evil. Evil derived its existence from some who had lost their wings by following the one who was first to lose his own wings.
Isaiah 14:12 · 2 passages

How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!

It is most clearly proved by these words that he who formerly was Lucifer and who “arose in the morning” has fallen from heaven. For if, as some suppose, he was a being of darkness, why is he said to have formerly been Lucifer or lightbearer? Or how could he “rise in the morning” who had in him no light at all?… So he was light once … when “his glory was turned into dust.”
How can we possibly suppose that what is said in many places by Scripture, especially in Isaiah, about Nebuchadnezzar is said about a human being? For no human being is said to have “fallen from heaven” or to have been “Lucifer” or the one who “arose every morning.”
