1 Kings 2:41-43

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?”
