1 Samuel 7:12 (KJV)

And as Samuel was offering up 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 discomfited them; and they were smitten before Israel.

And the men of Israel went out of Mizpeh, and pursued the Philistines, and smote them, until they came under Beth–car.

Then Samuel took a stone, and set it between Mizpeh and Shen, and called the name of it Eben–ezer, saying, Hitherto hath the Lord helped us.

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

And the cities which the Philistines had taken from Israel were restored to Israel, from Ekron even unto Gath; and the coasts thereof did Israel deliver out of the hands of the Philistines. And there was peace between Israel and the Amorites.
