Numbers 8:17-19

Living Bible

¹⁷ For all the firstborn among the people of Israel are mine, both men and animals; I claimed them for myself the night I killed all the firstborn Egyptians. ¹⁸ Yes, I have accepted the Levites in place of all the eldest sons of Israel. 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.”
