2 Samuel 3:20-21

3:20 When Abner, accompanied by twenty men, came to David in Hebron, David prepared a banquet for Abner and the men who were with him. 3:21 Abner said to David, “Let me leave so that I may go and gather all Israel to my lord the king so that they may make an agreement ¹  with you. Then you will rule over all that you desire.” So David sent Abner away, and he left in peace.
