'Rewards' in the Bible

A person of kindness rewards himself, but a cruel [person] harms his own flesh.

But if you tell me the dream and its explanation, you will receive gifts and rewards and great honor from me. Therefore, tell me the dream and its explanation."

Then Daniel answered and said before the king, "Let your gifts be for yourself or your rewards give to another; nevertheless, I will read the writing to the king and I will make known to him the explanation.
