Deuteronomy 29:24-28

24all the nations will say, ‘Why has the LORD done thus to this land? What caused the heat of this great anger?’ 25Then people will say, ‘It is because they abandoned the covenant of the LORD, the God of their fathers, which he made with them when he brought them out of the land of Egypt, 26and went and served other gods and worshiped them, gods whom they had not known and whom he had not allotted to them. 27Therefore the anger of the LORD was kindled against this land, bringing upon it all the curses written in this book, 28and the LORD uprooted them from their land in anger and fury and great wrath, and cast them into another land, as they are this day.’
