1 Samuel 7:7-11

7When the Philistine rulers heard that Israel had gathered at Mizpah, they mobilized their army and advanced. The Israelites were badly frightened when they learned that the Philistines were approaching.

8“Don’t stop pleading with the Lord our God to save us from the Philistines!” they begged Samuel.

9So Samuel took a young lamb and offered it to the Lord as a whole burnt offering. He pleaded with the Lord to help Israel, and the Lord answered him.

10Just as Samuel was sacrificing the burnt offering, the Philistines arrived to attack Israel. But the Lord spoke with a mighty voice of thunder from heaven that day, and the Philistines were thrown into such confusion that the Israelites defeated them.

11The men of Israel chased them from Mizpah to a place below Beth-car, slaughtering them all along the way.
