1 Sam 13:5

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

Now the Philistines assembled to fight against Israel with three thousand chariots, six thousand horsemen, and troops as numerous as the sand on the seashore. They went up and camped at Michmash, east of Beth-aven.
