2 Samuel 3:20-21
20 When Abner, who had twenty men with him, came to David at Hebron, David prepared a feast for him and his men.
21 Then Abner said to David, “Let me go at once and assemble all Israel for my lord the king, so that they may make a compact with you, and that you may rule over all that your heart desires.” So David sent Abner away, and he went in peace.
