19 And Ahimaaz the son of Zadok said, Let me run, I pray, and carry the king the news that Jehovah has avenged him of his enemies. 20 And Joab said to him, Thou shalt not be a bearer of news to-day, but thou shalt carry the news another day; but to-day thou shalt carry no news, because the king's son is dead. 21 Then said Joab to the Cushite, Go, tell the king what thou hast seen. And the Cushite bowed himself to Joab, and ran. 22 And Ahimaaz the son of Zadok said yet again to Joab, Come what may, let me, I pray thee, also run after the Cushite. And Joab said, Why wilt thou run, my son, seeing that there is no news suited [to thee]? 23 —But, come what may, let me run. And he said to him, Run. And Ahimaaz ran by the way of the plain, and outstripped the Cushite. 24 And David sat between the two gates; and the watchman went up to the roof of the gate, on to the wall, and lifted up his eyes and looked, and behold, a man running alone. 25 And the watchman cried, and told the king. And the king said, If he be alone, there is news in his mouth. And he came on and drew near. 26 And the watchman saw another man running; and the watchman called to the porter and said, Behold a man running alone. And the king said, He also is a bearer of news. 27 And the watchman said, I see the running of the foremost 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.
