1 Samuel 7:3-13

3And Samuel spoke to all the house of Israel, saying, If ye do return to the LORD with all your hearts, then put away the foreign gods and Ashtaroth from among you, and prepare your hearts to the LORD, and serve him only: and he will deliver you from the hand of the Philistines. 4Then the children of Israel put away Baalim and Ashtaroth, and served the LORD only. 5And Samuel said, Gather all Israel to Mizpeh, and I will pray for you to the LORD. 6And they gathered together at Mizpeh, and drew water, and poured it out before the LORD, and fasted on that day, and there said, We have sinned against the LORD. And Samuel judged the children of Israel in Mizpeh.

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. 12Then Samuel took a stone, and set it between Mizpeh and Shen, and called the name of it Ebenezer, saying, Thus far hath the LORD helped us.3

13So the Philistines were subdued, and they came no more into the land of Israel: and the hand of the LORD was against the Philistines all the days of Samuel.
