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 shall be kindled against them in that day, and I will forsake them, and I will hide my face from them, and they shall be devoured, and many evils and troubles shall come on them; so that they will say in that day, Haven't these evils come on us because our God is not among us?

18 I will surely hide my face in that day for all the evil which they shall have worked, in that they are turned to other gods.

19 Now therefore write you this song for you, and teach you it the children of Yisra'el: put it in their mouths, that this song may be a witness for me against the children of Yisra'el.

20 For when I shall have brought them into the land which I swore to their fathers, flowing with milk and honey, and they shall have eaten and filled themselves, and grown fat; then will they turn to other gods, and serve them, and despise me, and break my covenant.

21 It shall happen, when many evils and troubles are come on them, that this song shall testify before them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they frame this day, before I have brought them into the land which I swore.
