Luke 6:27-31

27But I say to you who hear, Love your enemies, do good to them who hate you, 28Bless them that curse you, and pray for them who despitefully use you. 29And to him that smiteth thee on the one cheek offer also the other; and him that taketh away thy cloke forbid not to take thy coat also. 30Give to every man that asketh of thee; and of him that taketh away thy goods ask them not again. 31And as ye would that men should do to you, do ye also to them likewise.
