1 Samuel 7:9-10

9So Samuel took a baby lamb. He gave it as a whole burnt offering to the Lord. Samuel asked the Lord to help the Israelites. The Lord answered his prayer in this way:

10While Samuel was giving the burnt offerings to the Lord, the Philistines moved nearer to attack the Israelites. But the Lord caused a very loud noise of thunder to frighten the Philistines. They became very confused and they started to run away from the Israelites.
