Exodus 18:21

ואתה תחזה MOREOVER THOU SHALT PROVIDE through the Holy Spirit that is upon thee (Mekhilta), אנשי חיל MEN OF ABILITY (but חיל may mean “wealth” and in this sense the words would mean) — rich men who will not need to flatter or to show favour (cf. Mekhilta). אנשי אמת MEN OF TRUTH — These are people commanding confidence (Mekhilta); who are deserving that one should rely upon their words — appoint these as judges because on account of this their words will be listened to. שנאי בצע HATING LUCRE — men who hate (pay no regard to) their property when it is to be made the matter of a law-suit (Mekhilta), in accordance with what we say: Any judge from whom one has to wring the money he owes only by means of a law-suit is no fitting judge (Bava Batra 58b). שרי אלפים OFFICERS OF THOUSANDS — there were six hundred such officers for the six hundred thousand men of Israel. שרי מאות OFFICERS OF HUNDREDS — there were six thousand of them. שרי חמשים OFFICERS OF FIFTIES — twelve thousand. שרי עשרת OFFICERS OF TENS — sixty thousand (Mekhilta, Sanhedrin 18a).

וְאַתָּ֣ה תֶחֱזֶ֣ה מִכׇּל־הָ֠עָ֠ם אַנְשֵׁי־חַ֜יִל יִרְאֵ֧י אֱלֹהִ֛ים אַנְשֵׁ֥י אֱמֶ֖ת שֹׂ֣נְאֵי בָ֑צַע וְשַׂמְתָּ֣ עֲלֵהֶ֗ם שָׂרֵ֤י אֲלָפִים֙ שָׂרֵ֣י מֵא֔וֹת שָׂרֵ֥י חֲמִשִּׁ֖ים וְשָׂרֵ֥י עֲשָׂרֹֽת׃

Moreover thou shalt provide out of all the people able men, such as fear God, men of truth, hating unjust gain; and place such over them, to be rulers of thousands, and rulers of hundreds, rulers of fifties, and rulers of tens;
