Numbers 31:26

22However the gold, and the silver, the bronze, the iron, the tin, and the lead,

23everything that may withstand the fire, you shall make to go through the fire, and it shall be clean; nevertheless it shall be purified with the water for impurity. All that doesn’t withstand the fire you shall make to go through the water.

24You shall wash your clothes on the seventh day, and you shall be clean. Afterward you shall come into the camp.”

25The LORD spoke to Moses, saying,

26“Count the plunder that was taken, both of man and of animal, you, and Eleazar the priest, and the heads of the fathers’ households of the congregation;

27and divide the plunder into two parts: between the men skilled in war, who went out to battle, and all the congregation.

28Levy a tribute to the LORD of the men of war who went out to battle: one soul of five hundred; of the persons, of the cattle, of the donkeys, and of the flocks.

29Take it from their half, and give it to Eleazar the priest, for the LORD’s wave offering.

30Of 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, of all the livestock, and give them to the Levites, who perform the duty of the LORD’s tabernacle.”
