民數記 31:30

從以色列人的一半之中，就是從人口、牛、驢、羊群、各樣牲畜中，每五十取一，交給看守耶和華帳幕的利未人。」

And of the children of Israel’s half, thou shalt take one portion of fifty, of the persons, of the beeves, of the asses, and of the flocks, of all manner of beasts, and give them unto the Levites, which keep the charge of the tabernacle of the LORD.
