1 Samuel 7:7-17

Now when the Philistines heard that the sons of Israel had gathered to Mizpah, the lords of the Philistines went up against Israel. And when the sons of Israel heard it, they were afraid of the Philistines. Then the sons of Israel said to Samuel, “Do not cease to cry to the LORD our God for us, that He may save us from the hand of the Philistines.” Samuel took a suckling lamb and offered it for a whole burnt offering to the LORD; and Samuel cried to the LORD for Israel and the LORD answered him. Now Samuel was offering up the burnt offering, and the Philistines drew near to battle against Israel. But the LORD thundered with a great thunder on that day against the Philistines and confused them, so that they were routed before Israel. The men of Israel went out of Mizpah and pursued the Philistines, and struck them down as far as below Beth-car. Then Samuel took a stone and set it between Mizpah and Shen, and named it Ebenezer, saying, “Thus far the LORD has helped us.” So the Philistines were subdued and they did not come anymore within the border of Israel. And the hand of the LORD was against the Philistines all the days of Samuel. The cities which the Philistines had taken from Israel were restored to Israel, from Ekron even to Gath; and Israel delivered their territory from the hand of the Philistines. So there was peace between Israel and the Amorites. Now Samuel judged Israel all the days of his life. He used to go annually on circuit to Bethel and Gilgal and Mizpah, and he judged Israel in all these places. Then his return was to Ramah, for his house was there, and there he judged Israel; and he built there an altar to the LORD.
