Deuteronomy 31:19 Meaning and Commentary

Deuteronomy 31:19

Now, therefore, write ye this song for you
Which was now dictated by the Lord, and given to Moses and Joshua to write, which is recorded in ( Deuteronomy 32:1-43 ) :

and teach it the children of Israel;
teach them by it, instructing them in the meaning of it: thus it was usual in ancient times to write things in verses, that they might be the more pleasingly attended to and regarded, and be longer retained in memory; and especially this practice was used with children, and still is:

put it in their mouths;
oblige them to get it by heart, or lay it up in their memories, and repeat it frequently, that it may be familiar to them, and not be forgotten by them:

that this song may be a witness for me against the children of Israel;
when in times to come they shall call to mind how in this song they were cautioned against such and such sins, and what they were threatened with should befall them on account of them, and how all things have come to pass exactly as foretold in it; which would be a testimony for God of his goodness to them, of his tender care of them, and concern for them, in the previous cautions he gave them; and of his foreknowledge of future events; and a testimony against them for their ingratitude and other sins.

Deuteronomy 31:19 In-Context

17 Then my anger will blaze forth against them. I will abandon them, hiding my face from them, and they will be devoured. Terrible trouble will come down on them, and on that day they will say, ‘These disasters have come down on us because God is no longer among us!’
18 At that time I will hide my face from them on account of all the evil they commit by worshiping other gods.
19 “So write down the words of this song, and teach it to the people of Israel. Help them learn it, so it may serve as a witness for me against them.
20 For I will bring them into the land I swore to give their ancestors—a land flowing with milk and honey. There they will become prosperous, eat all the food they want, and become fat. But they will begin to worship other gods; they will despise me and break my covenant.
21 And when great disasters come down on them, this song will stand as evidence against them, for it will never be forgotten by their descendants. I know the intentions of these people, even now before they have entered the land I swore to give them.”
