1 Samuel 7:3, 4, 10, 11

So Samuel said to all the Israelites, “If you are returning to the LORD with all your hearts, then rid yourselves of the foreign gods and the Ashtoreths and commit yourselves to the LORD and serve him only, and he will deliver you out of the hand of the Philistines.”

So the Israelites put away their Baals and Ashtoreths, and served the LORD only.

While Samuel was sacrificing the burnt offering, the Philistines drew near to engage Israel in battle. But that day the LORD thundered with loud thunder against the Philistines and threw them into such a panic that they were routed before the Israelites.

The men of Israel rushed out of Mizpah and pursued the Philistines, slaughtering them along the way to a point below Beth Kar.
