Ye have heard that it was said, an eye for an eye and a tooth for a tooth. But I say unto you, resist not him that is evil, but whosoever smited thee on thy right cheek, turn to him the other also. Even in modern times, this is not an easy way, this is not an easy way to live. Someone who's doing something to you, don't try to seek revenge. And this is a very different tone than a lot of what you might get in the Old Testament. Ye have heard that it was said, thou shalt love thy neighbor and hate thine enemy. But I say unto you, love your enemies and pray for them that persecute you.
