Saul took him that day, and would let him go no more home to his father's house.
      I. That Saul, who was now in possession of the crown, reposed a confidence in him, God so ordering it, that he might by his preferment at court be prepared for future service. Saul now took David home with him, and would not suffer him to return again to his retirement, 1 Samuel 18:2; 1 Samuel 18:2. And David having signalized himself above the men of war, in taking up the challenge which they declined, Saul set him over the men of war (1 Samuel 18:5; 1 Samuel 18:5), not that he made him general (Abner was in that post), but perhaps captain of the life-guard; or, though he was youngest, he ordered him to have the precedency, in recompence of his great services. He employed him in the affairs of government; and David went out whithersoever Saul sent him, showing himself as dutiful as he was bold and courageous. Those that hope to rule must first learn to obey. He had approved himself a dutiful son to Jesse his father, and now a dutiful servant to Saul his master; those that are good in one relation it is to be hoped will be so in another.
