1 Samuel 7:7-12

Now when the Philistines heard that the people of Israel had gathered at Mizpah, the lords of the Philistines went up against Israel. And when the people of Israel heard of it, they were afraid of the Philistines. And the people of Israel said to Samuel, “Do not cease to cry out to the LORD our God for us, that he may save us from the hand of the Philistines.” So 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. As Samuel was offering up the burnt offering, the Philistines drew near to attack Israel. But the LORD thundered with a mighty sound that day against the Philistines and threw them into confusion, and they were defeated before Israel. And the men of Israel went out from Mizpah and pursued the Philistines and struck them, as far as below Beth-car. Then Samuel took a stone and set it up between Mizpah and Shen and called its name Ebenezer; for he said, “Till now the LORD has helped us.”
