1 Samuel 17:1-2

Now the Philistines gathered together their armies to battle; and they were gathered together at Socoh, which belongeth to Judah, and encamped between Socoh and Azekah, in Ephes-dammim. And Saul and the men of Israel were gathered together, and encamped in the vale of Elah, and set the battle in array against the Philistines.
