2 Samuel 19:13

Of my bone, and of my flesh; Hebrew, art thou not my bone and my flesh?— a most near and dear relative. It is difficult to understand why in the Authorized Version this common metaphor in the Hebrew has been so meddled with, Ewald thinks that this purposed degradation of Joab and the substitution of Amasa in his stead was a wise and politic act. It was to some extent just, for Joab was a man stained with many murders; but politic it was not. Passing over the fact that Amasa had actually taken the command of the rebel army, he was an ambitious and selfish man, and could lay no claim to that sturdy fidelity which had characterized Joab throughout his long service. For all he had done had been for David's good, and his advice, however roughly given, had averted grave misfortunes. Joab's murder of Absalom was an act of wilful disobedience; but David had used Joab for a far meaner murder, committed, not for reasons of statesmanship; but for purposes of lust. The guilt of slaying Absalom was as nothing compared with that of slaying Uriah, nor was it so base as the assassination of Abner, which David had tolerated, though made angry by it. The dismissal of Joab could have been effected only by putting him to death, and this certainly he did not deserve at David's hands; and the attempt, unless carried out secretly, would have led to tumult and insurrection. Joab, too, was a far more skilful general than Amasa, who, with larger forces, had just suffered a disastrous defeat; and if Joab was removed secretly, his brother Abishai remained to avenge him. David was, in fact, blinded by love for the son whom for so many years he had treated with coldness. There was a strong reaction now in the father's mind, and under its influence he was prepared to sacrifice the nephew who had been faithful to him and saved him, for the nephew who had joined in Absalom's rebellion. But possibly it had an immediate good effect, as Amasa, assured of forgiveness and promotion, now took David's side.
