Deuteronomy 31:16-18

16The Lord said to Moses, “You are about to rest with your ancestors, and these people will soon prostitute themselves with the foreign gods of the land they are entering. They will abandon me and break the covenant I have made with them.

17My anger will burn against them on that day; I will abandon them and hide my face from them so that they will become easy prey. Many troubles and afflictions will come to them. On that day they will say, ‘Haven’t these troubles come to us because our God is no longer with us?’

18I will certainly hide my face on that day because of all the evil they have done by turning to other gods.
