2 Sm 3:17-21

17Abner then had a word with the elders of Israel: “For some time you have been wanting David as your king. 18Now take action, for the LORD has said of David: By David my servant I will save my people Israel from the power of the Philistines and from the power of all their enemies.” 19Abner also spoke with Benjamin, and then went to speak with David in Hebron concerning all that would be agreeable to Israel and to the whole house of Benjamin. 20When Abner, accompanied by twenty men, came to David in Hebron, David prepared a feast for Abner and for the men who were with him. 21Then Abner said to David, “I will now go to assemble all Israel for my lord the king, that they may make a covenant with you; you will then be king over all whom you wish to rule.” So David let Abner go on his way in peace.
