Saul knew David's voice, and said, Is this your voice, my son David? David said, It is my voice, my lord, O king.
      I. He reasons ironically with Abner, and keenly banters him. David knew well that it was from the mighty power of God that Abner and the rest of the guards were cast into so deep a sleep, and that God's immediate hand was in it; but he reproaches Abner as unworthy to be captain of the lifeguards, since he could sleep when the king his master lay so much exposed. By this it appears that the hand of God locked them up in this deep sleep that, as soon as ever David had got out of danger, a very little thing awakened them, even David's voice at a great distance roused them, 1 Samuel 26:14; 1 Samuel 26:14. Abner got up (we may suppose it early in a summer's morning) and enquired who called, and disturbed the king's repose. "It is I," says David, and then he upbraids him with his sleeping when he should have been upon his guard. Perhaps Abner, looking upon David as a despicable enemy and one that there was no danger from, had neglected to set a watch; however, he himself ought to have been more wakeful. David, to put him into confusion, told him, 1. That he had lost his honour (1 Samuel 26:15; 1 Samuel 26:15): "Art not thou a man? (so the word is), a man in office, that art bound, by the duty of thy place, to inspect the soldiery? Art not thou in reputation for a valiant man? So thou wouldst be esteemed, a man of such courage and conduct that there is none like thee; but now thou art shamed for ever. Thou a general! Thou, a sluggard!" 2. That he deserved to lose his head (1 Samuel 26:16; 1 Samuel 26:16): "You are all worthy to die, by martial law, for being off your guard, when you had the king himself asleep in the midst of you. Ecce signum--Behold this token. See where the king's spear is, in the hand of him whom the king himself is pleased to count his enemy. Those that took away this might as easily and safely have taken away his life. Now see who are the king's best friends, you that neglected him and left him exposed or I that protected him when he was exposed. You pursue me as worthy to die, and irritate Saul against me; but who is worthy to die now?" Note, Sometimes those that unjustly condemn others are justly left to fall into condemnation themselves.
