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 In that day my wrath will be moved against them, and I will be turned away from them, veiling my face from them, and destruction will overtake them, and unnumbered evils and troubles will come on them; so that in that day they will say, Have not these evils come on us because our God is not with us?

18 Truly, my face will be turned away from them in that day, because of all the evil they have done in going after other gods.

19 Make then this song for yourselves, teaching it to the children of Israel: put it in their mouths, so that this song may be a witness for me against the children of Israel.

20 For when I have taken them into the land named in my oath to their fathers, a land flowing with milk and honey, and they have made themselves full of food and are fat, then they will be turned to other gods and will give them worship, no longer honouring me or keeping my agreement.

21 Then when evils and troubles without number have overtaken them, this song will be a witness to them, for the words of it will be clear in the memories of their children: for I see the thoughts which are moving in their hearts even now, before I have taken them into the land of my oath.
