1 Samuel 7:8-10

8And the children of Israel said to Samuel, Cease not to cry to Jehovah our 1God for us, that he will save us out of the hand of the Philistines.

9And Samuel took a sucking-lamb, and offered it as a whole burnt-offering to Jehovah; and Samuel cried to Jehovah for Israel, and Jehovah answered him.

10And as Samuel was offering up the burnt-offering, the Philistines advanced to battle against Israel. And Jehovah thundered with a great thunder on that day upon the Philistines, and discomfited them; and they were routed before Israel.
