Deuteronomy 31:16-17

And the LORD said to Moses, “You will soon die. Then these people will not be loyal to me but will worship the foreign gods of the land they are entering. They will leave me, breaking the Agreement I made with them. Then I will become very angry at them, and 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, ‘It is because God is not with us that these terrible things are happening.’
