Deuteronomy 31:20
20 For after I have brought them to the land I promised to their ancestors—one flowing with milk and honey—and they eat their fill and become fat, then they will turn to other gods and worship them; they will reject me and break my covenant. 21 Then when many disasters and distresses overcome them this song will testify against them, for their descendants will not forget it. I know the intentions they have in mind today, even before I bring them to the land I have promised.” 22 So on that day Moses wrote down this song and taught it to the Israelites, 23 and the Lord commissioned Joshua son of Nun, “Be strong and courageous, for you will take the Israelites to the land I have promised them, and I will be with you.” 24 When Moses finished writing on a scroll the words of this law in their entirety, 25 he commanded the Levites who carried the ark of the Lord’s covenant, 26 “Take this scroll of the law and place it beside the ark of the covenant of the Lord your God. It will remain there as a witness against you, 27 for I know about your rebellion and stubbornness. Indeed, even while I have been living among you to this very day, you have rebelled against the Lord; you will be even more rebellious after my death!
Jubilees 1:7
6 And thus it will come to pass when all these things come upon them, that they will recognise that I am more righteous than they in all their judgments and in all their actions, and they will recognise that I have been truly with them. 7 And do thou write for thyself all these words which I declare unto, thee this day, for I know their rebellion and their stiff neck, before I bring them into the land of which I sware to their fathers, to Abraham and to Isaac and to Jacob, saying: ' Unto your seed will I give a land flowing with milk and honey. 8 And they will eat and be satisfied, and they will turn to strange gods, to (gods) which cannot deliver them from aught of their tribulation: and this witness shall be heard for a witness against them. For they will forget all My commandments, (even) all that I command them, and they will walk after the Gentiles, and after their uncleanness, and after their shame, and will serve their gods, and these will prove unto them an offence and a tribulation and an affliction and a snare.
Notes and References
"... The author tried to write in as “biblical” a Hebrew as possible, often peppering his discourse with phrases cited from the Pentateuch and elsewhere; this tendency is particularly pronounced in the opening chapter of the book, as the author tries to establish for readers that it is really Moses who is writing. Tis verse, like the preceding ones, is thus a patchwork of different biblical phrases: God tells Moses that He knows well Israel’s defiance and stubbornness, both of which appear together in Deuteronomy 31:27; He similarly refers to giving the land to your posterity, a phrase used frequently in Genesis (Genesis 12:7; 15:18; 24:7; 26:4, etc.) and it, along with When I bring them … with milk and honey, are recurrent phrases in the Pentateuch; see esp. Deuteronomy 31:20. When they eat and are full reflects Deuteronomy 31:20. The citation continues into the next verse with the words: they will turn to foreign gods … likewise from Deuteronomy 31:20 ..."
