Verse 18. - A lad saw them. Probably Absalom had sent out spies to watch the route which David had taken, to prevent any friends totaling him from the city, who would give him information as to the progress of events there. The word "lad" does not mean a boy; more probably he was one of the young men who formed Absalom's body guard, like the ten "lads," translated "young men," in 2 Samuel 18:15, Who bare Joab's armour. It Would be his duty to seize them, but when he tried to approach them, they fled, and made their way at full speed to Bahurim, where they were saved by the shrewdness and fidelity of a woman. Two such fleet runners would have had no difficulty in outstripping a boy, but one of Absalom's young men would have roused the neighbourhood to join in the pursuit. The well in his court really signifies a cistern for storing rainwater; but it was at that time dry, and served as a convenient hiding place for the two messengers.

17:1-21 Here was a wonderful effect of Divine Providence blinding Absalom's mind and influencing his heart, that he could not rest in Ahithophel's counsel, and that he should desire Hushai's advice. But there is no contending with that God who can arm a man against himself, and destroy him by his own mistakes and passions. Ahithophel's former counsel was followed, for God intended to correct David; but his latter counsel was not followed, for God meant not to destroy him. He can overrule all counsels. Whatever wisdom or help any man employs or affords, the success is from God alone, who will not let his people perish.Nevertheless, a lad saw them, and told Absalom,.... Saw them conversing with the girl, and departing for David's army; according to Josephus (o), they were some horsemen that saw them about two furlongs or a quarter mile from Jerusalem, and acquainted Absalom with it:

but they went both of them away quickly; made all the haste they could with their message to David:

and came to a man's house in Bahurim; where very probably they had been informed David had been, whither he came weary, and had refreshment, 2 Samuel 16:14; or rather, perceiving they were discovered and pursued, they turned in hither, the first place they came to, for safety:

which had a well in his court; which they observed, and was the reason of their turning in:

whither they went down; to hide themselves from their pursuers, it being dry, as sometimes wells were in the summertime: Josephus says (p), a woman let them down by a rope.
