1 Samuel 7:3-4, 10-11

And Samuel said to all the house of Israel, “If you are returning to the LORD with all your heart, then put away the foreign gods and the Ashtaroth from among you and direct your heart to the LORD and serve him only, and he will deliver you out of the hand of the Philistines.” So the people of Israel put away the Baals and the Ashtaroth, and they served the LORD only.

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.
