1SA 13:2

2 [Several years after he became king], he chose three thousand men from the Israeli army to go with him [to fight the Philistines]. Then he sent the other soldiers back home. Of the men he chose, 2,000 stayed with Saul at Micmash and in the hilly area near Bethel, and 1,000 stayed with [Saul’s son] Jonathan at Gibeah, in the area where the descendants of Benjamin lived.
