1 Samuel 7:3-4, 10-12

Then Samuel addressed the house of Israel: “If you are truly serious about coming back to GOD, clean house. Get rid of the foreign gods and fertility goddesses, ground yourselves firmly in GOD, worship him and him alone, and he’ll save you from Philistine oppression.” They did it. They got rid of the gods and goddesses, the images of Baal and Ashtoreth, and gave their exclusive attention and service to GOD.

While Samuel was offering the sacrifice, the Philistines came within range to fight Israel. Just then GOD thundered, a huge thunderclap exploding among the Philistines. They panicked—mass confusion!—and scattered before Israel. Israel poured out of Mizpah and gave chase, killing Philistines right and left, to a point just beyond Beth Car. Samuel took a single rock and set it upright between Mizpah and Shen. He named it “Ebenezer” (Rock of Help), saying, “This marks the place where GOD helped us.”
