And when the Lord saw it. The seeing of God, which is mentioned here, has reference to His forbearance in judgment: as if it were said, that He does not act hastily, and is not alienated from His children, without having duly weighed their case; in the same way as it is said elsewhere: "Because the cry of Sodom is great, I will go down now and see whether" it is so, and "I will know." (Genesis 18:20, 21) Assuredly God has no need to make any examination, since nothing escapes His eyes, however hidden it may be; but this going down and inquiring is contrasted with preposterous haste. Thus in this passage Moses shows that God was wroth, when he saw His sons and His daughters drawn away so faithlessly after their idols. Again, when he calls them God's children, he does not judge them to be so on account of their merits, but in reference to God's adoption, which, although it was canceled as regarded themselves, still had the effect of aggravating the guilt of their ingratitude. And for the same reason that he had just. said that God saw them, Moses introduces Him deliberating, as it were, that the time for punishing them might be perceived to be fully come. But we must notice the degrees; for God does not at once break forth into extreme severity, but is said to hide His face, that He might secretly consider what they would do: since this is a middle course between the manifest exhibition of His grace and favor, and the tokens of His wrath. God is, indeed, elsewhere said, in many passages, to hide His face, when He rejects men's prayers, and withdraws His aid; but here He assumes the character of a man who, when he sees that he produces no effect by acting, goes aside to some place, from whence he may quietly contemplate the result, And thus God's weariness of them is expressed; for when He at length saw that His efforts to control them were thrown away, He abandoned the care of them. It is a false inference, which some draw from hence, that men, when forsaken by God, recover themselves by the exercise of their own free-will; as if God sat calmly and inactively in a watch-tower expecting what they may do; inasmuch as this hiding of Himself has reference only to the outward manifestation of His grace. In a word, it is a similitude taken from the conduct of men, whereby God signifies that He is overcome with weariness, and will no more be the leader and guardian of the people, until it shall effectually appear that they are altogether intractable. And this is gathered from the reason, which is presently added, wherein He censures their forward nature and want of faith, as much as to say, that, after long trial, nothing remained for Him but to abandon them.

The anger of God at the apostasy of His people is stated in general terms in this verse; and the results of it are described, in words as of God Himself, in the next and following verses. These results consisted negatively in the withdrawal of God's favor Deuteronomy 32:20, and positively in the infliction of a righteous retribution.
Daughters - The women had their full share in the sins of the people. Compare Isaiah 3:16 ff; Isaiah 32:9 ff; Jeremiah 7:18; Jeremiah 44:15 ff.

When the Lord saw it, etc. - More literally, And the Lord saw it, and through indignation he reprobated his sons and his daughters. That is, When the Lord shall see such conduct, he shall be justly incensed, and so reject and deliver up to captivity his sons and daughters.

And when the LORD saw [it], he abhorred [them], because of the provoking of his (m) sons, and of his daughters.
(m) He calls them God's children, not to honour them, but to show them from what dignity they are fallen.

And when the Lord saw it,.... The disregard of the Jews to Christ, their forgetfulness of him, their disesteem and rejection of him; their continuance of sacrifices, when the great sacrifice was offered up; their setting up other messiahs and saviours, and the idol of their own righteousness, in opposition to the righteousness of Christ; all which not only as the omniscient God he saw, but took notice of, and considered, and did not at once pass judgment on them, at least did not immediately execute it, but waited some time to see how they would afterwards behave; for it was thirty years or more after the crucifixion of Christ that the utter destruction of the Jews came upon them:
he abhorred them; in his heart, despised them, and at last rejected them with contempt and abhorrence, very righteously and in just retaliation, see Zac 11:8; as for what before observed, so for what follows:
because of the provoking of his sons, and of his daughters; which is not to be understood of the Lord being provoked to wrath by the sins of those who called themselves or were called his sons and daughters; for these are such who were truly his sons and daughters, and different from those in Deuteronomy 32:20, said to be "children in whom is no faith": these are no other than the disciples and followers of Christ, that believed in him, both men and women, and so the children of God, his sons and his daughters by special grace; and the "provoking" of them is the wrath of the enemy against them, as the same word is used and rendered in Deuteronomy 32:27; and should be here, "because of wrath", or "indignation against his sons and his daughters" (m); meaning the affliction, distress, and persecution of them, through the wrath of the unbelieving Jews; for after the death of Christ they persecuted his apostles, they beat them and cast them into prison, and put some to death; a persecution was raised against the church at Jerusalem, in which Saul was concerned, who breathed out threatenings and slaughters against the disciples of the Lord, and haled men and women, the sons and daughters of God, and committed them to prison, and persecuted them to strange cities, and gave his voice to put them to death; and in the Gentile world, when the Gospel was carried there, the Jews stirred up the Gentiles everywhere against the followers of Christ, to harass and distress them; and this the Lord saw, and he abhorred them for it, and rejected them.
(m) "prae ira in filios suos", Pagninus; "propter iram in filios suos", Van Till; so Maimon. Moreh Nevochim, par. 1. c. 36.

The revolt of Israel was described in the foregoing verses, and here follow the resolves of Divine justice as to them. We deceive ourselves, if we think that God will be mocked by a faithless people. Sin makes us hateful in the sight of the holy God. See what mischief sin does, and reckon those to be fools that mock at it.

"And the Lord saw it, and rejected - from indignation at His sons and daughters." The object to "saw" may easily be supplied from the context: He saw the idolatry of the people, and rejected those who followed idols, and that because of indignation that His sons and daughters practised such abominations. The expression "he saw" simply serves to bring out the causal link between the apostasy and the punishment. ויּנאץ has been very well rendered by Kamphausen, "He resolved upon rejection," since Deuteronomy 32:20. clearly show that the rejection had only been resolved upon by God, and was not yet carried out. In what follows, Moses puts this resolution into the mouth of the Lord Himself.

His sons and daughters - Such they were by calling and profession.
