2 Samuel 3:39
And I am this day weak, though anointed king; and these men the sons of Zeruiah be too hard for me…
To his confidential servants David speaks his whole mind freely. He feels that some apology is needed for leaving the authors of this heinous crime unpunished. As an excuse for doing so he pleads his youth and weakness. Though he had been anointed king, his kingdom' was as yet far from being securely established, he could not dispense with his warlike nephews' help. He dared not order the execution of his best general. Probably the army would have interfered to prevent it. But he protests against their hardness and cruelty, and declares that Joab will not escape the Divine judgment for his crime. "It was one of those movements in which a king, even with the best intentions, must feel to his own heavy cost the weakness of everything human and the limits of human supremacy." Ewald's Hist. of Israel.
