(29) In the latter days.--A not uncommon prophetical expression, used with some considerable latitude. It occurs for the first time in Genesis 49:1. (See also Numbers 24:14 and Deuteronomy 4:30. ) Some would refer it to the "days of the Messiah," and make it almost a technical term. But a comparison of these few passages will show that it cannot be tied strictly to any one period.

Verse 29. - Ye will utterly corrupt yourselves; literally, corrupting, ye will corrupt (הַשְׁחַת תשׁחִתוּן, sc. דַרֵכֵיֶכם); i.e. your ways (cf. for the phrase, Genesis 6:12). The latter days; the after-time, the future, as in Deuteronomy 4:30; Numbers 24:14, etc. The work of your hands; the idols they might make (cf. Deuteronomy 4:28). By some, however, the phrase is interpreted of evil deeds in general

31:23-30 The solemn delivery of the book of the law to the Levites, to be deposited in, or rather by the side, of the ark, is again related. The song which follows in the next chapter is delivered to Moses, and by him to the people. He wrote it first, as the Holy Spirit taught him; and then spake it in the hearing of all the people. Moses tells them plainly, I know that after my death ye will utterly corrupt yourselves. Many a sad thought, no doubt, it occasioned to this good man; but his comfort was, that he had done his duty, and that God would be glorified in their dispersion, if not in their settlement, for the foundation of God stands sure.For I know that after my death,.... Which was just at hand, some time after that, not immediately; this he knew by a spirit of prophecy, namely, what follows:

ye will utterly corrupt yourselves; their ways, works, and manners, and so themselves; corrupt the worship of God by making idols, and serving them, which is the corruption chiefly intended:

and turn aside from the way which I have commanded you: from the way of the commandments of God, which Moses had given them in his name, and in which they were directed to walk; but, as here foretold, would wander and swerve from them as they did:

and evil will befall you in the latter days; not only in the times of the judges, and in the time of the Babylonish captivity, but in their present captivity, as they call it; which shows that the following song has things in it which respect times at a great distance, and even the present ones, and yet to come:

because ye will do evil in the sight of the Lord, to provoke him to anger through the work of your hands; their idols, idolatry being the evil chiefly designed, which is of all things the most provoking of the Lord.
