1 Samuel 23:24,25

But David and his men were in the wilderness of Maon Having heard what the Ziphites had undertaken, David disappointed their design by going into another place, with which, it is likely, they were not so well acquainted. For Maon was a distant wilderness from Ziph, though both were in the tribe of Judah. Saul also and his men went to seek him Hearing, it is likely, by the Ziphites, whither he was gone. Therefore he came down into a rock Some craggy, desolate place, where he thought Saul would not find him; or rather, into a cave which was in the rock, where, at first, he might think to hide himself; but, on further consideration, he removed from thence upon Saul's approach.
