Numbers 31:28-30

American Standard Version

²⁸ And levy a tribute unto Jehovah of the men of war that went out to battle: one soul of five hundred, both of the persons, and of the oxen, and of the asses, and of the flocks: ²⁹ take it of their half, and give it unto Eleazar the priest, for Jehovah’s heave-offering. 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.
