Numbers 8:19-21

Living Bible

¹⁹ And I will give the Levites as a gift to Aaron and his sons. The Levites will carry out the sacred duties required of the people of Israel in the Tabernacle, and will offer the people’s sacrifices, making atonement for them. There will be no plague among the Israelites—as there would be if the ordinary people entered the Tabernacle.”

²⁰ So Moses and Aaron and all the people of Israel dedicated the Levites, carefully following Jehovah’s instructions to Moses. ²¹ The Levites purified themselves and washed their clothes, and Aaron presented them to the Lord in a gesture of offering. He then performed the rite of atonement over them to purify them.
