2 Samuel 3:20-25

3:20 When Abner, accompanied by twenty men, came to David in Hebron, David prepared a banquet for Abner and the men who were with him. 3:21 Abner said to David, “Let me leave so that I may go and gather all Israel to my lord the king so that they may make an agreement with you. Then you will rule over all that you desire.” So David sent Abner away, and he left in peace.

Abner Is Killed

3:22 Now David’s soldiers and Joab were coming back from a raid, bringing a great deal of plunder with them. Abner was no longer with David in Hebron, for David had sent him away and he had left in peace. 3:23 When Joab and all the army that was with him arrived, Joab was told: “Abner the son of Ner came to the king; he sent him away, and he left in peace!”

3:24 So Joab went to the king and said, “What have you done? Abner has come to you! Why would you send him away? Now he’s gone on his way! 3:25 You know Abner the son of Ner! Surely he came here to spy on you and to determine when you leave and when you return and to discover everything that you are doing!”
