"Now write1 down for yourselves this song and teach it to the Israelites and have them sing it, so that it may be a witness2 for me against them.
When I have brought them into the land flowing with milk and honey, the land I promised on oath to their forefathers,3 and when they eat their fill and thrive, they will turn to other gods4 and worship them,5 rejecting me and breaking my covenant.621
And when many disasters and difficulties come upon them,7 this song will testify against them, because it will not be forgotten by their descendants. I know what they are disposed to do,8 even before I bring them into the land I promised them on oath."
So Moses wrote9 down this song that day and taught it to the Israelites.
