'Repay' in the Bible

The LORD will repay him for his bloodshed because, without my father David's consent he attacked and murdered two men more righteous and better than he, Ner's son Abner, the commander of Israel's army and Jether's son Amasa, commander of Judah's army.

The king also reminded Shimei, "You know all the evil things that you admit you did to my father David. Therefore the LORD is going to repay you for all of your evil.
