'Injures' in the Bible

“But he who fails to find me or sins against me injures himself;All those who hate me love and court death.”

But I say to you, do not resist an evil person [who insults you or violates your rights]; but whoever slaps you on the right cheek, turn the other toward him also [simply ignore insignificant insults or trivial losses and do not bother to retaliate—maintain your dignity, your self-respect, your poise].
