1 Samuel 7:9-13

Samuel took a nursing lamb and offered it as a whole burnt offering to the Lord; and Samuel cried out to the Lord for Israel, and the Lord answered him.

Now Samuel was offering up the burnt offering, and the Philistines advanced to battle Israel. But the Lord thundered with a great thunder on that day against the Philistines and confused them, so that they were struck down before Israel.

And the men of Israel came out of Mizpah and pursued the Philistines, and killed them as far as below Beth-car.

Then Samuel took a stone and placed it between Mizpah and Shen, and named it Ebenezer, saying, “So far the Lord has helped us.”

So the Philistines were subdued, and they did not come anymore within the border of Israel. And the hand of the Lord was against the Philistines all the days of Samuel.
