24 Now David was sitting between the two gates. And the watchman went up to the roof over the gate, to the wall, lifted his eyes and looked, and there was a man, running alone. 25 Then the watchman cried out and told the king. And the king said, "If he is alone, there is news in his mouth." And he came rapidly and drew near. 26 Then the watchman saw another man running, and the watchman called to the gatekeeper and said, "There is another man, running alone!" And the king said, "He also brings news." 27 So the watchman said, "I think the running of the first is like the running of Ahimaaz the son of Zadok." And the king said, "He is a good man, and comes with good news."

Commentary on 2 Samuel 18:19-33
(Read 2 Samuel 18:19-33)
By directing David to give God thanks for his victory, Ahimaaz prepared him for the news of his son's death. The more our hearts are fixed and enlarged, in thanksgiving to God for our mercies, the better disposed we shall be to bear with patience the afflictions mixed with them. Some think David's wish arose from concern about Absalom's everlasting state; but he rather seems to have spoken without due thought. He is to be blamed for showing so great fondness for a graceless son. Also for quarrelling with Divine justice. And for opposing the justice of the nation, which, as king, he had to administer, and which ought to be preferred before natural affection. The best men are not always in a good frame; we are apt to over-grieve for what we over-loved. But while we learn from this example to watch and pray against sinful indulgence, or neglect of our children, may we not, in David, perceive a shadow of the Saviour's love, who wept over, prayed for, and even suffered death for mankind, though vile rebels and enemies.
