1 Samuel 7:5-15

5 Then Samuel said, "Gather all Israel at Mizpah, and I will pray to the LORD for you."
6 So they gathered at Mizpah, and drew water and poured it out before the LORD, and fasted on that day, and said there, "We have sinned against the LORD." And Samuel judged the people of Israel at Mizpah.
7 Now when the Philistines heard that the people of Israel had gathered at Mizpah, the lords of the Philistines went up against Israel. And when the people of Israel heard of it they were afraid of the Philistines.
8 And the people 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."
9 So Samuel took a sucking lamb and offered it as a whole burnt offering to the LORD; and Samuel cried to the LORD for Israel, and the LORD answered him.
10 As Samuel was offering up the burnt offering, the Philistines drew near to attack Israel; but the LORD thundered with a mighty voice that day against the Philistines and threw them into confusion; and they were routed before Israel.
11 And the men of Israel went out of Mizpah and pursued the Philistines, and smote them, as far as below Beth-car.
12 Then Samuel took a stone and set it up between Mizpah and Jesha'nah, and called its name Ebene'zer; for he said, "Hitherto the LORD has helped us."
13 So the Philistines were subdued and did not again enter the territory of Israel. And the hand of the LORD was against the Philistines all the days of Samuel.
14 The cities which the Philistines had taken from Israel were restored to Israel, from Ekron to Gath; and Israel rescued their territory from the hand of the Philistines. There was peace also between Israel and the Amorites.
15 Samuel judged Israel all the days of his life.
