Deuteronomy 31:19-29

19“Now therefore write this song and teach it to the people of Israel. Put it in their mouths, that this song may be a witness for me against the people of Israel. 20For when I have brought them into the land flowing with milk and honey, which I swore to give to their fathers, and they have eaten and are full and grown fat, they will turn to other gods and serve them, and despise me and break my covenant. 21And when many evils and troubles have come upon them, this song shall confront them as a witness (for it will live unforgotten in the mouths of their offspring). For I know what they are inclined to do even today, before I have brought them into the land that I swore to give.” 22So Moses wrote this song the same day and taught it to the people of Israel. 23And the LORD commissioned Joshua the son of Nun and said, “Be strong and courageous, for you shall bring the people of Israel into the land that I swore to give them. I will be with you.” 24When Moses had finished writing the words of this law in a book to the very end, 25Moses commanded the Levites who carried the ark of the covenant of the LORD, 26“Take this Book of the Law and put it by the side of the ark of the covenant of the LORD your God, that it may be there for a witness against you. 27For I know how rebellious and stubborn you are. Behold, even today while I am yet alive with you, you have been rebellious against the LORD. How much more after my death! 28Assemble to me all the elders of your tribes and your officers, that I may speak these words in their ears and call heaven and earth to witness against them. 29For I know that after my death you will surely act corruptly and turn aside from the way that I have commanded you. And in the days to come evil will befall you, because you will do what is evil in the sight of the LORD, provoking him to anger through the work of your hands.”
