There was a hill close by, so the Israel mob went up from the valley on to that hill. From there they saw the Philistia mob on the hill on the other side of the valley.
Saul gathered the Israel soldiers together, and they camped in the valley called Elah. They got ready there to fight with the Philistia soldiers.
One of the Philistia soldiers was a really big man called Goliath, and he was from a town called Gath. He was really tall, about 3 metres.
