1 Sam 8:12

וְלָשׂ֣וּם ל֔וֹ שָׂרֵ֥י אֲלָפִ֖ים וְשָׂרֵ֣י חֲמִשִּׁ֑ים וְלַחֲרֹ֤שׁ חֲרִישׁוֹ֙ וְלִקְצֹ֣ר קְצִיר֔וֹ וְלַעֲשׂ֥וֹת כְּלֵֽי־מִלְחַמְתּ֖וֹ וּכְלֵ֥י רִכְבּֽוֹ׃

He will appoint some for himself as commanders of thousands and of fifties, and others to plow his ground, to reap his harvest, to make his weapons of war, and to equip his chariots.
