1 Samuel 7:8-10

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

9And Samuel took a sucking lamb, and offered it for a burnt offering wholly unto Yhwh: and Samuel cried unto Yhwh for Israel; And Yhwh heard him.2 10And as Samuel was offering up the burnt offering, the Philistines drew near to battle against Israel: But Yhwh thundered with a great thunder on that day upon the Philistines, and discomfited them; and they were smitten before Israel.
