[19] Now therefore write ye this song for you, and teach it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel. [20] For when I shall have brought them into the land which I sware unto their fathers, that floweth with milk and honey; and they shall have eaten and filled themselves, and waxen fat; then will they turn unto other gods, and serve them, and provoke me, and break my covenant. [21] And it shall come to pass, when many evils and troubles are befallen them, that this song shall testify against them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they go about, even now, before I have brought them into the land which I sware. [22] Moses therefore wrote this song the same day, and taught it the children of Israel. [23] And he gave Joshua the son of Nun a charge, and said, Be strong and of a good courage: for thou shalt bring the children of Israel into the land which I sware unto them: and I will be with thee. [24] And it came to pass, when Moses had made an end of writing the words of this law in a book, until they were finished, [25] That Moses commanded the Levites, which bare the ark of the covenant of the LORD, saying, [26] Take this book of the law, and put it in the side of the ark of the covenant of the LORD your God, that it may be there for a witness against thee. [27] For I know thy rebellion, and thy stiff neck: behold, while I am yet alive with you this day, ye have been rebellious against the LORD; and how much more after my death? [28] Gather unto me all the elders of your tribes, and your officers, that I may speak these words in their ears, heaven and earth to record against them. [29] For I know that after my death ye will utterly yourselves, and turn aside from the way which I have commanded you; and evil will befall you in the latter days; because ye will do evil in the sight of the LORD, to provoke him to anger through the work of your hands. [30] And Moses spake in the ears of all the congregation of Israel the words of this song, until they were ended.
