1 Samuel 27:8

The Gezrites were anciently seated in other places, Joshua 12:12, Joshua 16:3, but for some reasons not now known they changed their seats, as was then very usual, and seated themselves, and had for some considerable time lived, near the Amalekites. The Amalekites; the remnant of those whom Saul destroyed, 1Sa 15, who fled from his sword, and retired into remote and desert places.
