An Eye for an Eye

You have heard that it was said, ‘An eye for an eye and a tooth for a tooth.  But I tell you not to resist an evil person. But whoever slaps you on your right cheek, turn the other to him also.
– Matthew 5:38-39

The Bible does not teach “an eye for an eye” in this verse.  Jesus simply said to His listeners that they have “heard it said”.  That doesn’t mean He’s promoting the concept.
