Doubtless in slaying Absalom, in spite of the king's entreaty, Joab had inflicted an agonising wound on the pride and tenderness of his master. But Absalom was in open rebellion, and Joab may have held that David's probable pardon of the beautiful rebel would be both weak and fatal. This death was inflicted in a manner needlessly cruel, but might have been excused as a death inflicted on the battle-field, though probably Joab had many an old grudge to pay off besides the burning of his barley field. After Absalom's rebellion David foolishly and unjustly offered the commandership of the army to his nephew Amasa. Amasa was the son of his sister Abigail by an Ishmaelite father, named Jether.[112] Joab simply would not tolerate being superseded in the command which he had earned by lifelong and perilous services. With deadly treachery, in which men have seen the antitype of the world's worst crime, Joab invited his kinsman to embrace him, and drove his sword into his bowels. David had heard, or perhaps had seen, the revolting spectacle which Joab presented, with the blood of war shed in peace, dyeing his girdle and streaming down to his shoes with its horrible crimson. Yet, even by that act, Joab had once more saved David's tottering throne. The Benjamite Sheba, son of Bichri, was making head in a terrible revolt, in which he had largely enlisted the sympathy of the northern tribes, offended by the overbearing fierceness of the men of Judah. Amasa had been either incompetent or half-hearted in suppressing this dangerous rising. It had only collapsed when the army welcomed back the strong hand of Joab. But whatever had been the crimes of Joab they had been condoned. David, on more than one occasion, had helplessly cried, "What have I to do with you, ye sons of Zeruiah?" "I am this day weak though anointed king, and these men, the sons of Zeruiah, are too hard for me." But he had done nothing, and, whether with or against his will, they continued to hold their offices near his person. David did not remind Solomon of the murder of Absalom, nor of the words of menace--words as bold as any subject ever uttered to his sovereign--with which Joab had imperiously hushed his wail over his worthless son. Those words had openly warned the king that, if he did not alter his line of conduct, he should be king no more. They were an insult which no king could pardon, even if he were powerless to avenge. But Joab, like David himself, was now an old man. The events of the last few days had shown that his power and influence were gone. He may have had something to fear from Bathsheba as the wife of Uriah and the granddaughter of Ahithophel; but his adhesion to the cause of Adonijah had doubtless been chiefly due to jealousy of the ever-growing influence of the priestly soldier Benaiah, son of Jehoiada, who had so evidently superseded him in his master's favour. However that may be, the historian faithfully records that David, on his death-bed, neither
