And David did so as the Lord commanded him,.... In all things he was obedient to the command of God; Saul was not: he got behind the army of the Philistines, as he was directed; and when he heard the sound in the mulberry trees, he arose and fell upon his enemies:
and smote the Philistines from Geba until thou come to Gazer; or from Gibeon, as in 1 Chronicles 14:16; a city in the tribe of Benjamin, near to which this battle was fought, and where the pursuit began, which was carried as far as Gazer, a city that lay on the borders of the Philistines, as Josephus says b; and so far they were pursued, and were smitten as they fled; and, according to Bunting c, it was a space of eighteen miles.
