2 Samuel 3:26-39

After Joab left David, he sent messengers after Abner, and they brought him back from the well of Sirah. But David did not know this. When Abner arrived at Hebron, Joab took him aside into the gateway. He acted as though he wanted to talk with Abner in private, but Joab stabbed him in the stomach, and Abner died. Abner had killed Joab’s brother Asahel, so Joab killed Abner to pay him back. Later when David heard the news, he said, “My kingdom and I are innocent forever of the death of Abner son of Ner. The LORD knows this. Joab and his family are responsible for this. May his family always have someone with sores or with a skin disease. May they always have someone who must lean on a crutch. May some of his family be killed in war. May they always have someone without food to eat.” (Joab and his brother Abishai killed Abner, because he had killed their brother Asahel in the battle at Gibeon.) Then David said to Joab and to all the people with Joab, “Tear your clothes and put on rough cloth to show how sad you are. Cry for Abner.” King David himself followed the body of Abner. They buried Abner in Hebron, and David and all the people cried at Abner’s grave. King David sang this funeral song for Abner. “Did Abner die like a fool? His hands were not tied. His feet were not in chains. He fell at the hands of evil men.” Then all the people cried again for Abner. They came to encourage David to eat while it was still day. But he made a promise, saying, “May God punish me terribly if I eat bread or anything else before the sun sets!” All the people saw what happened, and they agreed with what the king was doing, just as they agreed with everything he did. That day all the people of Judah and Israel understood that David did not order the killing of Abner son of Ner. David said to his officers, “You know that a great man died today in Israel. Even though I am the appointed king, I feel empty. These sons of Zeruiah are too much for me. May the LORD give them the punishment they should have.”
