Deuteronomy 31:16-17

16And the Lord said to Moses: “You are going to rest with your ancestors, and these people will soon prostitute themselves to the foreign gods of the land they are entering. They will forsake me and break the covenant I made with them. 17And in that day I will become angry with them and forsake them; I will hide my face from them, and they will be destroyed. Many disasters and calamities will come on them, and in that day they will ask, ‘Have not these disasters come on us because our God is not with us?’
