1 Kings 2:41-46

41But it was reported to Solomon that Shimei had gone from Jerusalem to Gath and back.

42So the king sent someone and summoned Shimei. He said to him: “Didn’t I make you swear by Adonai and forewarned you, saying: ‘Know for certain that on the day you depart and go anywhere else, you shall surely die’? You even said to me: ‘The saying is good; I have heard it.’

43Why then haven’t you kept the oath of Adonai and the commandment that I charged you with?”

44The king added to Shimei: “You know all the evil, which your heart should acknowledge, that you did to my father David. Therefore Adonai will return your evil on your own head.

45But King Solomon shall be blessed and the throne of David established before Adonai forever.”

46So the king commanded Benaiah son of Jehoiada, and he went out and struck him down, so that he died. Thus the kingdom was secured in the hand of Solomon.
