Verse 24. - David sat between the two gates. The gateway was in a tower in the city walls, and David was sitting in the space between the inner and outer gates. Over this space was a chamber, mentioned in ver. 33, while the sentinel was posted upon the front wall over the outer gate.

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.And David sat between the two gates,.... Of the city of Mahanaim; which being a fortified place had two walls, one within another, and in each wall a gate; and between these David sat, waiting for news of the battle:

and the watchman went up to the roof over the gate unto the wall; the gate to the outward wall, over which was a tower, and on that a flat roof; to which the watchman went to observe if he could see an express coming; no doubt by David's orders:

and lifted up his eyes and looked; that is, very diligently and wistfully:

and, behold, a man running alone: which made him the more observable, and was the more likely to be a messenger.
