Here, 1. Saul gets information of David's movements and acts offensively. The Ziphites came to him and told him where David now was, in the same place where he was when they formerly betrayed him, Sa1 23:19. Perhaps (though it is not mentioned) Saul had given them intimation, under-hand, that he continued his design against David, and would be glad of their assistance. If not, they were very officious to Saul, aware of what would please him, and very malicious against David, to whom they despaired of ever reconciling themselves, and therefore they stirred up Saul (who needed no such spur) against him, Sa1 26:1. For aught we know, Saul would have continued in the same good mind that he was in (Sa1 24:17), and would not have given David this fresh trouble, if the Ziphites had not put him on. See what need we have to pray to God that, since we have so much of the tinner of corruption in our own hearts, the sparks of temptation may be kept far from us, lest, if they come together, we be set on fire of hell. Saul readily caught at the information, and went down with an army of 3000 men to the place where David hid himself, Sa1 26:2. How soon do unsanctified hearts lose the good impressions which their convictions have made upon them and return with the dog to their vomit!

2.David gets information of Saul's movements and acts defensively. He did not march out to meet and fight him; he sought only his own safety, not Saul's ruin; therefore he abode in the wilderness (Sa1 26:3), putting thereby a great force upon himself, and curbing the bravery of his own spirit by a silent retirement, showing more true valour than he could have done by an irregular resistance. (1.) He had spies who informed him of Saul's descent, that he had come in very deed (Sa1 26:4.); for he would not believe that Saul would deal so basely with him till he had the utmost evidence of it. (2.) He observed with his own eyes how Saul was encamped, Sa1 26:5. He came towards the place where Saul and his men had pitched their tents, so near as to be able, undiscovered, to take a view of their entrenchments, probably in the dusk of the evening.

Three thousand chosen men - Though they knew that David was but six hundred strong, yet Saul thought it was not safe to pursue such an able general with a less force than that mentioned in the text; and, that he might the better depend on them, they were all elect or picked men out of the whole of his army.

Then Saul arose,.... Immediately, glad of an opportunity to seize on David, having the same disposition towards him as ever; and perhaps had repented he had not laid hold on him when he followed him out of the cave:

and went down to the wilderness of Ziph: or towards it:

having three thousand chosen men of Israel; young men, so called, because usually chosen for business, and for war particularly, rather than old men; the same number he took with him when he sought him at Engedi, Sa1 24:2,

to seek David in the wilderness of Ziph; where or whereabouts he was informed by the Ziphites he was.
