Numbers 31:29-31

King James Version

²⁹ Take it of their half, and give it unto Eleazar the priest, for an heave offering of the Lord.

³⁰ 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.

³¹ And Moses and Eleazar the priest did as the Lord commanded Moses.
