Deuteronomy 31:16-18

16And the Lord said to Moses: “Behold, you will rest with your fathers; and this people will rise and play the harlot with the gods of the foreigners of the land, where they go to be among them, and they will forsake Me and break My covenant which I have made with them.

17Then My anger shall be aroused against them in that day, and I will forsake them, and I will hide My face from them, and they shall be devoured. And many evils and troubles shall befall them, so that they will say in that day, ‘Have not these evils come upon us because our God is not among us?’

18And I will surely hide My face in that day because of all the evil which they have done, in that they have turned to other gods.
