1 Samuel 7:10-12

As Samuel was offering up the burnt offering, the Philistines approached for the battle against Israel. Then the LORD thundered with a great voice that day against the Philistines and threw them into confusion, and they were defeated and fled before Israel. And the men of Israel came out of Mizpah and pursued the Philistines, and struck them down as far as [the territory] below Beth-car. Then Samuel took a stone and set it between Mizpah and Shen, and he named it Ebenezer (stone of help), saying, “Thus far the LORD has helped us.”
