Numbers 31:27-31

and divide the spoils between the warriors who went to battle and all the congregation.

Also, collect a tribute tax for the Lord from the men of war who went to battle, one in five hundred of the persons, of the cattle, of the donkeys, and of the sheep;

take it from their half and give it to Eleazar the priest, as an offering to the Lord.

And from the sons of Israel’s half, you shall take one drawn from every fifty of the persons, of the cattle, of the donkeys, and of the sheep, from all the animals; and give them to the Levites who perform the duty of the tabernacle of the Lord.”

Moses and Eleazar the priest did just as the Lord had commanded Moses.
