Commentary for I Samuel 13:5

וּפְלִשְׁתִּ֞ים נֶאֶסְפ֣וּ ׀ לְהִלָּחֵ֣ם עִם־יִשְׂרָאֵ֗ל שְׁלֹשִׁ֨ים אֶ֤לֶף רֶ֙כֶב֙ וְשֵׁ֤שֶׁת אֲלָפִים֙ פָּרָשִׁ֔ים וְעָ֕ם כַּח֛וֹל אֲשֶׁ֥ר עַל־שְׂפַֽת־הַיָּ֖ם לָרֹ֑ב וַֽיַּעֲלוּ֙ וַיַּחֲנ֣וּ בְמִכְמָ֔שׂ קִדְמַ֖ת בֵּ֥ית אָֽוֶן׃

And the Philistines assembled themselves together to fight with Israel, thirty thousand chariots, and six thousand horsemen, and people as the sand which is on the sea-shore in multitude; and they came up, and pitched in Michmas, eastward of Beth-aven.
