Deuteronomy 29:20-21

20The Lord will never forgive that person. He will be very angry with him. The Lord will punish him in all the terrible ways that are written in this book. The Lord will destroy him completely so that his family name comes to an end.

21The Lord will make that person separate from all the Israelite tribes and he will punish him very much. All the troubles that the Lord promises in this covenant will happen to that person, as this book of God's Law says.
