2 Samuel 3:17-21

17And Abner conferred with the elders of Israel, saying, "For some time past you have been seeking David as king over you.

18Now then bring it about, for the Lord has promised David, saying, 'By the hand of my servant David I will save my people Israel from the hand of the Philistines, and from the hand of all their enemies.'"

19Abner also spoke to Benjamin. And then Abner went to tell David at Hebron all that Israel and the whole house of Benjamin thought good to do.

20When Abner came with twenty men to David at Hebron, David made a feast for Abner and the men who were with him.

21And Abner said to David, "I will arise and go and will gather all Israel to my lord the king, that they may make a covenant with you, and that you may reign over all that your heart desires." So David sent Abner away, and he went in peace.
