Deuteronomy 30:6-8 King James Version (KJV)
6 And the Lord thy God will circumcise thine heart, and the heart of thy seed, to love the Lord thy God with all thine heart, and with all thy soul, that thou mayest live.
7 And the Lord thy God will put all these curses upon thine enemies, and on them that hate thee, which persecuted thee.
8 And thou shalt return and obey the voice of the Lord, and do all his commandments which I command thee this day.
Romans 12:19-21 King James Version (KJV)
19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord.
20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head.
21 Be not overcome of evil, but overcome evil with good.
