As Samuel was offering up the burnt offering, the Philistines drew near to battle against Israel; but Yahweh thundered with a great thunder on that day on the Philistines, and confused them; and they were struck down before Israel.
YLT
and Samuel is causing the burnt-offering to go up—and the Philistines have drawn nigh to battle against Israel—and Jehovah doth thunder with a great noise, on that day, upon the Philistines, and troubleth them, and they are smitten before Israel.
