1 Samuel 7:7-11

7And the Philistines heard that the children of Israel were gathered together at Mizpah; and the lords of the Philistines went up against Israel; and the children of Israel heard [it], and were afraid of the Philistines.

8And the children of Israel said to Samuel, Cease not to cry to Jehovah our 1God for us, that he will save us out of the hand of the Philistines.

9And Samuel took a sucking-lamb, and offered it as a whole burnt-offering to Jehovah; and Samuel cried to Jehovah for Israel, and Jehovah answered him.

10And as Samuel was offering up the burnt-offering, the Philistines advanced to battle against Israel. And Jehovah thundered with a great thunder on that day upon the Philistines, and discomfited them; and they were routed before Israel.

11And the men of Israel went out of Mizpah, and pursued the Philistines, and smote them, as far as below Beth-car.
