1 Kings 2:7-9

⁷But show kindness to the sons of Barzillai the Gileadite, and let them be amongst those who eat at your table; for so they came to me when I fled from Absalom your brother.

⁸“Behold, there is with you Shimei the son of Gera, the Benjamite of Bahurim, who cursed me with a grievous curse in the day when I went to Mahanaim; but he came down to meet me at the Jordan, and I swore to him by the LORD, saying, ‘I will not put you to death with the sword.’

⁹Now therefore don’t hold him guiltless, for you are a wise man; and you will know what you ought to do to him, and you shall bring his grey head down to Sheol with blood.”
