1 Samuel 23:15

And David saw that Saul was come out to seek his life,.... Either he saw him with his bodily eyes from the top of the mountain where he was, 1 Samuel 23:14; or he perceived, he understood by information given him by his friends, it may be by Jonathan, or by spies he sent to observe his motions:

and David [was] in the wilderness of Ziph in a wood; where he and his men could hide themselves among the trees in it; sometimes he was in a mountain in this wilderness, and sometimes in a wood, where he thought himself the safest; thus was this great man obliged to shift about for his safety.
