2 Samuel 3:22 - 3:25
22 And behold, the servants of David and Joab came from a raid and brought much spoil with them; but Abner was not with David in Hebron, for he had sent him away, and he had gone in peace. 23 Now Joab and all the army that was with him arrived, and they told Joab, saying, “Abner the son of Ner came to the king, and he has sent him away, and he has gone in peace.” 24 Then Joab came to the king and said, “What have you done? Behold, Abner came to you; why then have you sent him away and he is already gone? 25 You know Abner the son of Ner, that he came to deceive you and to know of your going out and your coming in and to know all that you are doing.”
