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 I'll get angry, oh so angry! I'll walk off and leave them on their own, won't so much as look back at them. Then many calamities and disasters will devastate them because they are defenseless. They'll say, 'Isn't it because our God wasn't here that all this evil has come upon us?'

18 But I'll stay out of their lives, keep looking the other way because of all their evil: they took up with other gods!

19 "But for right now, copy down this song and teach the People of Israel to sing it by heart. They'll have it then as my witness against them.

20 When I bring them into the land that I promised to their ancestors, a land flowing with milk and honey, and they eat and become full and get fat and then begin fooling around with other gods and worshiping them,

21 and then things start falling apart, many terrible things happening, this song will be there with them as a witness to who they are and what went wrong. Their children won't forget this song; they'll be singing it. Don't think I don't know what they are already scheming to do, and they're not even in the land yet, this land I promised them."
