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 I will become very angry at them, and I will leave them. I will turn away from them, and they will be destroyed. Many terrible things will happen to them. Then they will say, 'It is because God is not with us that these terrible things are happening.'

18 I will surely turn away from them then, because they have done wrong and have turned to other gods.

19 "Now write down this song and teach it to the Israelites. Then have them sing it, because it will be my witness against them.

20 When I bring them into the land I promised to their ancestors, a fertile land, they will eat as much as they want and get fat. Then they will turn to other gods and serve them. They will reject me and break my Agreement.

21 Then when many troubles and terrible things happen to them, this song will testify against them, because the song will not be forgotten by their descendants. I know what they plan to do, even before I take them into the land I promised them."
