16 And the Lord said to Moses, “You will soon die. Then these people will not be loyal to me. They will worship the foreign gods of the land they are entering. They will leave me. And they will break the agreement I made with them.
17 Then I will become very angry at them. I will leave them. I will turn away from them. And they will be destroyed. Many terrible things will happen to them. Then they will say, ‘God is not with us. That is why these terrible things are happening.’
18 I will turn away from them then. They have done wrong. They have turned to other gods.
19 “Now write down this song. And teach it to the Israelites. Then have them sing it. It will testify against them.
20 I will bring them into the land I promised to their ancestors. It is a land where much food grows. They will eat as much as they want and get fat. But then they will turn to other gods and serve them. They will reject me and break my agreement.
21 Then many troubles and terrible things will happen to them. And this song will testify against them. The song will not be forgotten by their descendants. I know what they plan to do, even before I take them into the land I promised them.”
22 So Moses wrote down the song that day. And he taught it to the Israelites.
