1 Kings 2:41-43

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?”
