Deuteronomy 29:20-21

20“The Lord would not spare him; for then the anger of the Lord and His jealousy would burn against that man, and every curse that is written in this book would settle on him, and the Lord would blot out his name from under heaven.

21And the Lord would separate him from all the tribes of Israel for adversity, according to all the curses of the covenant that are written in this Book of the Law,
