31 And David saith unto Joab, and unto all the people who 'are' with him, 'Rend your garments, and gird on sackcloth, and mourn before Abner;' and king David is going after the bier. 32 And they bury Abner in Hebron, and the king lifteth up his voice, and weepeth at the grave of Abner, and all the people weep; 33 and the king lamenteth for Abner, and saith:—'As the death of a fool doth Abner die? 34 Thy hands not bound, And thy feet to fetters not brought nigh! As one falling before sons of evil—Thou hast fallen!' and all the people add to weep over him. 35 And all the people come to cause David to eat bread while yet day, and David sweareth, saying, 'Thus doth God to me, and thus He doth add, for—before the going in of the sun, I taste no bread or any other thing.'

Commentary on 2 Samuel 3:22-39

(Read 2 Samuel 3:22-39)

Judgments are prepared for such scorners as Abner; but Joab, in what he did, acted wickedly. David laid Abner's murder deeply to heart, and in many ways expressed his detestation of it. The guilt of blood brings a curse upon families: if men do not avenge it, God will. It is a sad thing to die like a fool, as they do that any way shorten their own days, and those who make no provision for another world. Who would be fond of power, when a man may have the name of it, and must be accountable for it, yet is hampered in the use of it? David ought to have done his duty, and then trusted God with the issue. Carnal policy spared Joab. The Son of David may long delay, but never fails to punish impenitent sinners. He who now reigns upon the throne of David, has a kingdom of a nobler kind. Whatever He doeth, is noticed by all his willing people, and is pleasing to them.
