'Reward' in the Bible

And David, hearing that Nabal was dead, said, May the Lord be praised, who has taken up my cause against Nabal for the shame which he put on me, and has kept back his servant from evil, and has sent on Nabal's head the reward of his evil-doing. And David sent word to Abigail, desiring to take her as his wife.

And the Lord will give to every man the reward of his righteousness and his faith: because the Lord gave you into my hands today, and I would not put out my hand against the man who has been marked with the holy oil.
