Numbers 31:25-29

25And the LORD spoke to Moses, saying, 26Take the sum of the prey that was taken, both of man and of beast, thou, and Eleazar the priest, and the chief fathers of the congregation:1 27And divide the prey into two parts; between them that took the war upon them, who went out to battle, and between all the congregation: 28And levy a tribute to the LORD of the men of war who went out to battle: one soul of five hundred, both of the persons, and of the cattle, and of the donkeys, and of the sheep: 29Take it of their half, and give it to Eleazar the priest, for an heave offering of the LORD.
