Deuteronomy 29:19-20

19When such a person hears the words of this oath he secretly blesses himself and says, “I will have peace though I continue to walk with a stubborn spirit.” This will destroy the watered ground with the parched.

20The Lord will be unwilling to forgive him, and his intense anger will rage against that man; all the curses written in this scroll will fall upon him and the Lord will obliterate his name from memory.
