1 Kings 2:6

4Then the LORD may establish his word which he spoke concerning me, saying, ‘If your children are careful of their way, to walk before me in truth with all their heart and with all their soul, there shall not fail you,’ he said, ‘a man on the throne of Israel.’

5“Moreover you know also what Joab the son of Zeruiah did to me, even what he did to the two captains of the armies of Israel, to Abner the son of Ner and to Amasa the son of Jether, whom he killed, and shed the blood of war in peace, and put the blood of war on his sash that was around his waist and in his sandals that were on his feet.

6Do therefore according to your wisdom, and don’t let his gray head go down to Sheol in peace.

7But show kindness to the sons of Barzillai the Gileadite, and let them be among 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.’
