Deuteronomy 29:24-27

“All nations would say, ‘Why has the LORD done so to this land? What does the heat of this great anger mean?’ Then people would say: ‘Because they have forsaken the covenant of the LORD God of their fathers, which He made with them when He brought them out of the land of Egypt; for they went and served other gods and worshiped them, gods that they did not know and that He had not given to them. Then the anger of the LORD was aroused against this land, to bring on it every curse that is written in this book.
