2 Samuel 3:28-37

28Afterward, David heard about this and said, “I and my kingdom are forever guiltless before the LORD concerning the blood of Abner son of Ner. 29May it whirl over the head of Joab and over the entire house of his father, and may the house of Joab never be without one having a discharge or skin disease, or one who leans on a staff or falls by the sword or lacks food.”

30(Joab and his brother Abishai murdered Abner because he had killed their brother Asahel in the battle at Gibeon.)

31Then David ordered Joab and all the people with him, “Tear your clothes, put on sackcloth, and mourn before Abner.” And King David himself walked behind the funeral bier.

32When they buried Abner in Hebron, the king wept aloud at Abner’s tomb, and all the people wept. 33And the king sang this lament for Abner:

And all the people wept over him even more.

35Then all the people came and urged David to eat something while it was still day, but David took an oath, saying, “May God punish me, and ever so severely, if I taste bread or anything else before the sun sets!”

36All the people took note and were pleased. In fact, everything the king did pleased them. 37So on that day all the troops and all Israel were convinced that the king had no part in the murder of Abner son of Ner.
