1 Samuel 7:5-12

And Samuel said, Gather all Israel to Mizpah, and I will pray for you unto Jehovah. And they gathered together to Mizpah, and drew water, and poured it out before Jehovah, and fasted on that day, and said there, We have sinned against Jehovah. And Samuel judged the children of Israel in Mizpah. And when the Philistines heard that the children of Israel were gathered together to Mizpah, the lords of the Philistines went up against Israel. And when the children of Israel heard it, they were afraid of the Philistines. And the children of Israel said to Samuel, Cease not to cry unto Jehovah our God for us, that he will save us out of the hand of the Philistines. 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. 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. And the men of Israel went out of Mizpah, and pursued the Philistines, and smote them, until they came under Beth-car. 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.
