Numbers 31:25-29

Then the Lord spoke to Moses, saying,

“You and Eleazar the priest and the heads of the fathers’ households of the congregation take a count of the spoils that were captured, both of people and of livestock;

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.
