2 Samuel 3:20

16Her husband went with her, weeping as he went, and followed her to Bahurim. Then Abner said to him, “Go! Return!” and he returned.

17Abner had communication with the elders of Israel, saying, “In times past, you sought for David to be king over you.

18Now then do it! For the LORD has spoken of David, saying, ‘By the hand of my servant David, I will save my people Israel out of the hand of the Philistines, and out of the hand of all their enemies.’”

19Abner also spoke in the ears of Benjamin; and Abner went also to speak in the ears of David in Hebron all that seemed good to Israel and to the whole house of Benjamin.

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

21Abner 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 soul desires.” David sent Abner away; and he went in peace.

22Behold, David’s servants and Joab came from a raid and brought in a great plunder with them; but Abner was not with David in Hebron, for he had sent him away, and he had gone in peace.

23When Joab and all the army who was with him had come, they told Joab, “Abner the son of Ner came to the king, and he has sent him away, and he has gone in peace.”

24Then Joab came to the king and said, “What have you done? Behold, Abner came to you. Why is it that you have sent him away, and he is already gone?
