Numbers 3:8-10

New Century Version

⁸ The Levites must take care of everything in the Meeting Tent and serve the people of Israel by doing the work in the Holy Tent. ⁹ Give the Levites to Aaron and his sons; of all the Israelites, the Levites are given completely to him. ¹⁰ Appoint Aaron and his sons to serve as priests, but anyone else who comes near the holy things must be put to death.”
