Numbers 31:21-31 King James Version (KJV)
21 And Eleazar the priest said unto the men of war which went to the battle, This is the ordinance of the law which the Lord commanded Moses;
22 Only the gold, and the silver, the brass, the iron, the tin, and the lead,
23 Every thing that may abide the fire, ye shall make it go through the fire, and it shall be clean: nevertheless it shall be purified with the water of separation: and all that abideth not the fire ye shall make go through the water.
24 And ye shall wash your clothes on the seventh day, and ye shall be clean, and afterward ye shall come into the camp.
25 And the Lord spake unto Moses, saying,
26 Take 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:
27 And divide the prey into two parts; between them that took the war upon them, who went out to battle, and between all the congregation:
28 And levy a tribute unto the Lord of the men of war which went out to battle: one soul of five hundred, both of the persons, and of the beeves, and of the asses, and of the sheep:
29 Take it of their half, and give it unto Eleazar the priest, for an heave offering of the Lord.
30 And of the children of Israel's half, thou shalt take one portion of fifty, of the persons, of the beeves, of the asses, and of the flocks, of all manner of beasts, and give them unto the Levites, which keep the charge of the tabernacle of the Lord.
31 And Moses and Eleazar the priest did as the Lord commanded Moses.
