1 Kings 2:41-46

41When Solomon was told that Shimei had gone from Jerusalem to Gath and had returned, 42the king summoned Shimei and said to him, “Did I not make you swear by the LORD and warn you, ‘On the day you leave and go elsewhere, know for sure that you will die’? And you told me, ‘The sentence is fair; I will comply.’ 43So why have you not kept your oath to the LORD and the command that I gave you?”

44The king also said, “You know in your heart all the evil that you did to my father David. Therefore the LORD will bring your evil back upon your head. 45But King Solomon will be blessed and David’s throne will remain secure before the LORD forever.”

46Then the king commanded Benaiah son of Jehoiada, and he went out and struck Shimei down, and he died. Thus the kingdom was firmly established in the hand of Solomon.
