Deuteronomy 29:24-27

“And all the surrounding nations will ask, ‘Why has the LORD done this to this land? Why was he so angry?’ “And the answer will be, ‘This happened because the people of the land abandoned the covenant that the LORD, the God of their ancestors, made with them when he brought them out of the land of Egypt. Instead, they turned away to serve and worship gods they had not known before, gods that were not from the LORD. That is why the LORD’s anger has burned against this land, bringing down on it every curse recorded in this book.
