2 Samuel 3:22-23

22Just then David’s soldiers and Joab returned from a raid and brought a large amount of plundered goods with them. Abner was not with David in Hebron because David had dismissed him, and he had gone in peace.

23When Joab and his whole army arrived, Joab was informed, “Abner son of Ner came to see the king, the king dismissed him, and he went in peace.”
