1 Samuel 7:9-10

9Samuel took 1a suckling lamb and offered it for a whole burnt offering to the Lord; and Samuel cried to the Lord for Israel and 2the Lord answered him.

10Now Samuel was offering up the burnt offering, and the Philistines drew near to battle against Israel. But 3the Lord thundered with a great 4thunder on that day against the Philistines and 5confused them, so that they were 6routed before Israel.
