20When Abner and twenty of his men came to David at Hebron, David held a feast for them.
21Then Abner said to David, “Let me go at once, and I will gather all Israel to my lord the king, that they may make a covenant with you, and that you may rule over all that your heart desires.” So David dismissed Abner, and he went in peace.
22Just then David’s soldiers and Joab returned from a raid, bringing with them a great plunder. But Abner was not with David in Hebron because David had sent him on his way in peace.
23When Joab and all his troops arrived, he was informed, “Abner son of Ner came to see the king, who sent him on his way in peace.”
