1 Sam 4:10

וַיִּלָּחֲמ֣וּ פְלִשְׁתִּ֗ים וַיִּנָּ֤גֶף יִשְׂרָאֵל֙ וַיָּנֻ֨סוּ֙ אִ֣ישׁ לְאֹהָלָ֔יו וַתְּהִ֥י הַמַּכָּ֖ה גְּדוֹלָ֣ה מְאֹ֑ד וַיִּפֹּל֙ מִיִּשְׂרָאֵ֔ל שְׁלֹשִׁ֥ים אֶ֖לֶף רַגְלִֽי׃

So the Philistines fought, and Israel was defeated, and each man fled to his tent. The slaughter was very great—thirty thousand foot soldiers of Israel fell.
