Matthew 5:39, 44-45

but I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.

But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; that ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
