2 Samuel 3:32

30So Joab and Abishai his brother killed Abner, because he had killed their brother Asahel at Gibeon in the battle.

31David said to Joab and to all the people who were with him, “Tear your clothes, and clothe yourselves with sackcloth, and mourn in front of Abner.” King David followed the bier.

32They buried Abner in Hebron; and the king lifted up his voice and wept at Abner’s grave; and all the people wept.

33The king lamented for Abner, and said, “Should Abner die as a fool dies?

34Your hands weren’t bound, and your feet weren’t put into fetters. As a man falls before the children of iniquity, so you fell.” All the people wept again over him.
