Verses 21-23. - Ye have compassion on me. There is something pitiable in Saul's answer. He had brooded over his rejection from being king, and the many indications that David was to be his successor, till he had become the prey of abject melancholy. He evidently regarded himself as a wronged and injured man, while David to his diseased imagination was ever conspiring against him and plotting his murder. With much prolixity he encourages them still to keep a close watch upon all David's movements, so as to know his place where his haunt is. Literally, "his place where his foot will be," the place whither he goes for rest and refuge. The reason he gives for this long and close observation of David's doings is that it is told him that he dealeth very subtilly. That is, according to Saul's information, he behaved with the utmost prudence, ever keeping a careful look out against surprise, and using much skill to conceal his movements and to provide for his escape from danger. Finally, they are to return with the certainty - with trustworthy and accurate information, and then Saul will gather his forces and search David out throughout all the thousands of Judah. These are the larger divisions of the territory of the tribe (Numbers 1:16; Numbers 10:4), throughout which Saul will hunt for him till he has got him into his power.

23:19-29 In the midst of his wickedness, Saul affected to speak the language of piety. Such expressions, without suitable effects, can only amuse or deceive those who hear, and those who use them. This mountain was an emblem of the Divine Providence coming between David and the destroyer. Let us not be dismayed at the prospect of future difficulties, but stay ourselves upon Him who is wonderful in counsel and excellent in working. Sooner than his promise shall fail, he will commission Philistines to effect our escape, at the very moment when our case appears most desperate. God requires entire dependence on him, If ye will not believe, surely ye shall not be established, Isa 7:9.And Saul said, blessed be ye of the Lord,.... He highly commends them for the offer they made to him, blesses God for them, and desires the blessing of God upon them for it:

for ye have compassion on me; pitied him on account of the troubles he met with from his son-in-law, were sorry for him, and sympathized with him, which others did not, of which he complained, 1 Samuel 22:8.
