Then David went over to the other side,.... To a hill on the other side, opposite to Hachilah, where Saul lay encamped; or "passed over the passage" q, the valley that lay between the two hills, and perhaps passed over a brook that ran in the valley, which is not unusual; so Josephus r says, that he went over a brook and came to the top of a mountain:
and stood on the top of an hill afar off; he chose the top of an hill, that his voice might be heard at a distance, as it might in a clear air, and still night; and to be afar off, that he might the better make his escape, should an attempt be made to pursue him:
a great space [being] between them; a large valley lying between the two hills.
