1 Samuel 4:9-11

Young's Literal Translation

⁹ Strengthen yourselves, and become men, O Philistines, lest ye do service to Hebrews, as they have done to you -- then ye have become men, and have fought.'

¹⁰ And the Philistines fight, and Israel is smitten, and they flee each to his tents, and the blow is very great, and there fall of Israel thirty thousand footmen;

¹¹ and the ark of God hath been taken, and the two sons of Eli have died, Hophni and Phinehas.
