1 Samuel 7:7-11

7And when the Philistines heard that the children of Israel were gathered together at Mizpeh, the lords of the Philistines went up against Israel. And when the children of Israel heard it, they were afraid of the Philistines. 8And the children of Israel said to Samuel, Cease not to cry to the LORD our God for us, that he will save us from the hand of the Philistines.1 9And Samuel took a sucking lamb, and offered it for a burnt offering wholly to the LORD: and Samuel cried to the LORD for Israel; and the LORD heard him.2 10And as Samuel was offering the burnt offering, the Philistines drew near to battle against Israel: but the LORD thundered with a great thunder on that day upon the Philistines, and smote them; and they were smitten before Israel. 11And the men of Israel went out of Mizpeh, and pursued the Philistines, and smote them, until they came under Bethcar.
