Numbers 31:28-30

Young's Literal Translation

²⁸ and thou hast raised a tribute to Jehovah from the men of war, who go out to the host, one body out of five hundred, of man, and of the herd, and of the asses, and of the flock;

²⁹ from their half ye do take, and thou hast given to Eleazar the priest -- the heave-offering of Jehovah.

³⁰ `And from the sons of Israel's half thou dost take one possession out of fifty, of man, of the herd, of the asses, and of the flock, of all the cattle, and thou hast given them to the Levites keeping the charge of the tabernacle of Jehovah.'
