Numbers 31:28

Take the sum of the prey that was taken, both of man and of animal, you, and Eleazar the priest, and the heads of the fathers' [houses] of the congregation;

and divide the prey into two parts: between the men skilled in war, who went out to battle, and all the congregation.

take it of their half, and give it to Eleazar the priest, for Yahweh's wave offering.

Of the children of Israel's half, you shall take one drawn out of every fifty, of the persons, of the cattle, of the donkeys, and of the flocks, [even] of all the livestock, and give them to the Levites, who perform the duty of the tabernacle of Yahweh.
