2 Samuel 3:31-35

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

32They buried Abner in Hebron; and the king raised his voice and wept at the grave of Abner, and all the people wept.

33And the king sang a dirge (funeral song) over Abner and said, “Should Abner [the great warrior] die as a fool dies?

34Your hands were not bound, nor your feet put in fetters; As a man falls before the wicked, so you have fallen.” And all the people wept again over him.

35All the people came to urge David to eat food while it was still day; but David took an oath, saying, “May God do so to me, and more also, if I taste bread or anything else before the sun sets.”
