1 Samuel 7:7-13 New Revised Standard Version (NRSV)
7 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 The people of Israel said to Samuel, “Do not cease to cry out to the Lord our God for us, and pray 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; Samuel cried out 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 struck them down as far as beyond Beth-car.
12 Then Samuel took a stone and set it up between Mizpah and Jeshanah,[a] and named it Ebenezer;[b] for he said, “Thus far the Lord has helped us.” 13 So the Philistines were subdued and did not again enter the territory of Israel; the hand of the Lord was against the Philistines all the days of Samuel.
