1Sam 17:1-3

David and Goliath 1Now the Philistines gathered their armies for battle; they were gathered at Socoh, which belongs to Judah, and encamped between Socoh and Azekah, in Ephes-dammim.2Saul and the Israelites gathered and encamped in the valley of Elah, and formed ranks against the Philistines.3The Philistines stood on the mountain on the one side, and Israel stood on the mountain on the other side, with a valley between them.
