2 Samuel 3:31-35

31David instructed Joab and all the people who were with him, “Tear your clothes! Put on sackcloth! Lament before Abner!” Now King David followed behind the funeral bier.

32So they buried Abner in Hebron. The king cried loudly over Abner’s grave and all the people wept too.

33The king chanted the following lament for Abner: “Should Abner have died like a fool?

34Your hands were not bound, and your feet were not put into irons. You fell the way one falls before criminals.” All the people wept over him again.

35Then all the people came and encouraged David to eat food while it was still day. But David took an oath saying, “God will punish me severely if I taste bread or anything whatsoever before the sun sets!”
