In 2 Samuel 3 the Spirit of God marks the progress of things. “There was long war between the house of Saul and the house of David: but David waxed stronger and stronger, and the house of Saul waxed weaker and weaker.” This gives occasion for showing out the end of Abner's history, as well as of Ish-bosheth's, in the next chapter. The continual fighting furnished at last what Joab had long wished for—the opportunity to take Abner aside and speak with him quietly, thus lawlessly to avenge the blood of his brother, while he got rid of a great opponent disposed for peace with his master. But David bore witness in his fasting and tears how deeply he felt Abner's death, and how truly he judged Joab's iniquity, though alas his power was not equal to his heart. Hence he could do no more at present than say “to Joab and all the people that were with him, Rend your clothes, and gird you with sackcloth, and mourn before Abner. And king David himself followed the bier.”
It was a fine feeling, and this, I am persuaded, from higher than human sources. But while his was a generous heart, there was that which, being of God, gave it its true direction, and sustained it in power spite of all circumstances. Clearly I speak now of where he was directly guided of God. “And the king lamented over Abner,” just as suitably as he had before lamented over Jonathan and his father, “and said, Died Abner as a fool dieth? Thy hands were not bound, nor thy feet put into fetters: as a man falleth before wicked men, so fellest thou.” He judged truly even of his own commander-in-chief, as one may call Joab—at least the one that was to be so formally before long. “And all the people wept again over him. And when all the people came to cause David to eat meat while it was yet day, David sware, saying, So do God to me, and more also, if I taste bread, or ought else, till the sun be down. And all the people took notice of it, and it pleased them: as whatsoever the king did pleased the people. For all the people and all Israel understood that day that it was not of the king to slay Abner the son of Ner.”
At the same time the king confesses what a sinful thing had been done, and his own weakness. “Know ye not that there is a prince and a great man fallen this day in Israel? And I am this day weak.” How true! “I am this day weak, though anointed king; and these men the sons of Zeruiah be too hard for me: Jehovah shall reward the doer of evil according to his wickedness.” A single eye is always full of light; and though David could not shake off those on whom indeed he was too dependent as the supports of his throne, nevertheless he does judge what was unworthy of the name of Jehovah, and what was abhorrent to his own soul. Weakness or worse must always be till Jesus take the throne.
