And smite the city - David's kind nature induced him to spare Jerusalem the horrors of a siege, and the risk of being taken by assault. He had no standing army with which to resist this sudden attack from so unexpected a quarter. Possibly too he remembered Nathan's prophecy 2 Samuel 12:10-12.

David said - Arise - let us flee - This, I believe, was the first time that David turned his back to his enemies. And why did he now flee? Jerusalem, far from not being in a state to sustain a siege, was so strong that even the blind and the lame were supposed to be a sufficient defense for the walls, see 2 Samuel 5:6. And he had still with him his faithful Cherethites and Pelethites; besides six hundred faithful Gittites, who were perfectly willing to follow his fortunes. There does not appear any reason why such a person, in such circumstances, should not act on the defensive; at least till he should be fully satisfied of the real complexion of affairs. But he appears to take all as coming from the hand of God; therefore he humbles himself, weeps, goes barefoot, and covers his head! He does not even hasten his departure, for the habit of mourners is not the habit of those who are flying before the face of their enemies. He sees the storm, and he yields to what he conceives to be the tempest of the Almighty.

And David said unto all his servants that were with him at Jerusalem,.... His courtiers and ministers of state, the officers of his household, as many of them as were with him in the city; for some of them very probably were in the country, as Ahithophel was, and some might be along with Absalom, whom he had invited to his peace offerings:

arise, and let us flee; it is much that a man of such courage and valour as David should be so intimidated at once as to make a flight as soon as he heard of a conspiracy forming against him:

for we shall not else escape from Absalom; his fears ran so high, that he fancied he would be upon them presently:

make speed to depart, lest he overtake us suddenly; which still more clearly shows the panic he was in:

and bring evil upon us; kill them, or make them prisoners:

and smite the city with the edge of the sword; the inhabitants of it, should they make resistance.

And David said unto all his servants that were with him at Jerusalem, Arise, and let us flee; for we shall not else escape from {h} Absalom: make speed to depart, lest he overtake us suddenly, and bring evil upon us, and smite the city with the edge of the sword.

(h) Whose heart he saw that Satan had so possessed that he would leave no mischief unattempted.

15:14 Let us flee - For though the fort of Zion was strong, and he might have defended himself there; yet he had not laid in provisions for a long siege; and, if he had been once besieged there, Absalom would have got speedy possession of his whole kingdom; whereas if he marched abroad, he might raise a considerable army for his defence. Besides, the greatest part of Jerusalem could not be well defended against him.

14. David said . Arise, and let us flee-David, anxious for the preservation of the city which he had beautified, and hopeful of a greater support throughout the country, wisely resolved on leaving Jerusalem.

15:13-23 David determined to quit Jerusalem. He took this resolve, as a penitent submitting to the rod. Before unrighteous Absalom he could justify himself, and stand out; but before the righteous God he must condemn himself, and yield to his judgments. Thus he accepts the punishment of his sin. And good men, when they themselves suffer, are anxious that others should not be led to suffer with them. He compelled none; those whose hearts were with Absalom, to Absalom let them go, and so shall their doom be. Thus Christ enlists none but willing followers. David cannot bear to think that Ittai, a stranger and an exile, a proselyte and a new convert, who ought to be encouraged and made easy, should meet with hard usage. But such value has Ittai for David's wisdom and goodness, that he will not leave him. He is a friend indeed, who loves at all times, and will adhere to us in adversity. Let us cleave to the Son of David, with full purpose of heart, and neither life nor death shall separate us from his love.
