David sat between the two gates - He was probably in the seat of justice. Before the gate of the city it is supposed there was an enclosure, which had its gate also; David sat in the space between these two doors. Over the larger gate there appears to have been a turret, on which a sentinel or watchman stood continually, and gave information of what he saw in the country.

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.

David was sitting between the two gates of Mahanaim waiting for tidings of the result of the battle. The two gates are the outer and inner gate of the fortified city wall, between which there was a small court, where David was sitting. The watchman then went up to the roof of the gate by the wall, probably the outer gate in the city wall, and as he looked he saw a man running alone.

And David sat between the two {h} gates: and the watchman went up to the roof over the gate unto the wall, and lifted up his eyes, and looked, and behold a man running alone.

(h) He sat in the gate of the city of Mahanaim.

18:24 Gates - For the gates of the cities then were, as now they are, large and thick; and for the greater security, had two gates, one more outward, the other inward. Here he sat, that he might hear tidings when any came into the city.

24-32. David sat between the two gates-that is, in the tower-house on the wall that overhung the gate of Mahanaim. Near it was a watchtower, on which a sentinel was posted, as in times of war, to notify every occurrence. The delicacy of Ahimaaz' communication was made up by the unmistakable plainness of Cushi's. The death of Absalom was a heavy trial, and it is impossible not to sympathize with the outburst of feeling by which David showed that all thoughts of the victory he had won as a king were completely sunk in the painful loss he had sustained as a father. The extraordinary ardor and strength of his affection for this worthless son break out in the redundancy and vehemence of his mournful ejaculations.

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.
