1 Samuel 13:2, 16

Saul chose for himself 3,000 men of Israel; of whom 2,000 were with him in Michmash and in the hill country of Bethel, while 1,000 were with Jonathan at Gibeah of Benjamin. But he sent the rest of the people away, each one to his own tent.

Saul and his son Jonathan and the people with them were staying in Geba of Benjamin, while the Philistines camped at Michmash.
