Numbers 3:8-10

New Catholic Bible

⁸ They will take care of all of the furnishings of the tent of meeting and attend to the needs of the people of Israel as they minister in the tabernacle. ⁹ You will give the Levites to Aaron and his sons; they are dedicated to him from among the people of Israel. ¹⁰ You will appoint Aaron and his sons, and they will serve as priests. Anyone else who draws near is to be put to death.”
