1 Samuel 7:9-12

ASV(i) 9 And Samuel took a sucking lamb, and offered it for a whole burnt-offering unto Jehovah: and Samuel cried unto Jehovah for Israel; and Jehovah answered him. 10 And as Samuel was offering up the burnt-offering, the Philistines drew near to battle against Israel; but Jehovah thundered with a great thunder on that day upon the Philistines, and discomfited them; and they were smitten down before Israel. 11 And the men of Israel went out of Mizpah, and pursued the Philistines, and smote them, until they came under Beth-car.
12 Then Samuel took a stone, and set it between Mizpah and Shen, and called the name of it Eben-ezer, saying, Hitherto hath Jehovah helped us.
