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 1:8
7 “Now you write this entire message which I am telling you today, because I know their defiance and their stubbornness even before I bring them into the land which I promised by oath to Abraham, Isaac, and Jacob: 'To your posterity I will give the land which flows with milk and honey'. When they eat and are full, 8 they will turn to foreign gods — to ones which will not save them from any of their afflictions. Then this testimony will serve as evidence. 9 For they will forget all my commandments — everything that I command them — and will follow the nations, their impurities, and their shame. They will serve their gods, and this will prove an obstacle for them — an affliction, a pain, and a trap.
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 ..."
