2 Samuel 3:31-39

31Then David said to Joab and to all the people who were with him, "Tear your clothes and put on sackcloth and mourn before Abner." And King David followed the bier.

32They buried Abner at Hebron. And the king lifted up his voice and wept at the grave of Abner, and all the people wept.

33And the king lamented for Abner, saying, "Should Abner die as a fool dies?

34Your hands were not bound; your feet were not fettered; as one falls before the wicked you have fallen." And all the people wept again over him.

35Then all the people came to persuade David to eat bread while it was yet day. But David swore, saying, "God do so to me and more also, if I taste bread or anything else till the sun goes down!"

36And all the people took notice of it, and it pleased them, as everything that the king did pleased all the people.

37So all the people and all Israel understood that day that it had not been the king's will to put to death Abner the son of Ner.

38And the king said to his servants, "Do you not know that a prince and a great man has fallen this day in Israel?

39And I was gentle today, though anointed king. These men, the sons of Zeruiah, are more severe than I. The Lord repay the evildoer according to his wickedness!"
