I Samuel 7:10-12

Now as Samuel was offering up the burnt offering, the Philistines drew near to battle against Israel. But the LORD thundered with a loud thunder upon the Philistines that day, and so confused them that they were overcome before Israel. And the men of Israel went out of Mizpah and pursued the Philistines, and drove them back as far as below Beth Car. Then Samuel took a stone and set it up between Mizpah and Shen, and called its name Ebenezer, saying, “Thus far the LORD has helped us.”
