24 So Joab went to the king. He said, "What have you done? Abner came to you. Why did you let him get away? Now he's gone!
25 You know what Abner, the son of Ner, is like. He came to trick you. He wanted to watch your every move. He came to find out everything you are doing."
26 Then Joab left David. He sent messengers to get Abner. They brought Abner back from the well of Sirah. But David didn't know about it.
27 When Abner returned to Hebron, Joab took him to one side. He brought him to the entrance of the city gate. Joab acted as if he wanted to speak to him in private. But he really wanted to get even with him. That's because Abner had spilled the blood of Joab's brother Asahel. So Joab stabbed him in the stomach. And Abner died.
28 Later on, David heard about it. He said, "I and the people of my kingdom aren't guilty of spilling the blood of Abner, the son of Ner. We are free of blame forever in the sight of the Lord.
29 "May Joab and his whole family line be held accountable for spilling Abner's blood! May someone in Joab's family always have an open sore or skin disease. May someone in his family always have to use a crutch to walk. May someone in his family be killed with a sword. And may someone in his family never have enough food to eat."
30 Joab and his brother Abishai murdered Abner. They did it because he had killed their brother Asahel in the battle at Gibeon.
