1 Kings 2:8-9

“And remember, Shimei son of Gera, the Benjaminite, is here with you. He cursed me the day I went to Mahanaim. But when he came down to meet me at the Jordan River, I promised him before the Lord, ‘Shimei, I will not kill you.’ But you should not leave him unpunished. You are a wise man, and you will know what to do to him, but you must be sure he is killed.”
