Números 31:30

30 From the Israelites' half, select one out of every fifty, whether people, cattle, donkeys, sheep or other animals. Give them to the Levites, who are responsible for the care of the Lord's tabernacle."

30 And of the children of Israel's half, thou shalt take one drawn out of every fifty, of the persons, of the oxen, of the asses, and of the flocks, [even] of all the cattle, and give them unto the Levites, that keep the charge of the tabernacle of Jehovah.
