Matthew 5:39, 44-45

but I say unto you, Resist not him that is evil: but whosoever smiteth thee on thy right cheek, turn to him the other also.

but I say unto you, Love your enemies, and pray for them that persecute you; that ye may be sons of your Father who is in heaven: for he maketh his sun to rise on the evil and the good, and sendeth rain on the just and the unjust.
