2 Samuel 3:31-35

31David then ordered Joab and all the people who were with him, “Tear your clothes, put on sackcloth, and mourn over Abner.” And King David walked behind the coffin.

32When they buried Abner in Hebron, the king wept aloud at Abner’s tomb. All the people wept,

33and the king sang a lament for Abner: Should Abner die as a fool dies?

34Your hands were not bound, your feet not placed in bronze shackles. You fell like one who falls victim to criminals. And all the people wept over him even more.

35Then they came to urge David to eat food while it was still day, but David took an oath: “May God punish me and do so severely if I taste bread or anything else before sunset!”
