Numbers 18:27-29

New Century Version

²⁷ I will accept your offering just as much as I accept the offerings from others, who give new grain or new wine. ²⁸ In this way you will present an offering to the Lord as the other Israelites do. When you receive a tenth from the Israelites, you will give a tenth of that to Aaron, the priest, as the Lord’s share. ²⁹ Choose the best and holiest part from what you are given as the portion you must give to the Lord.’
