Numbers 8:18-20

Evangelical Heritage Version

¹⁸ But I have taken the Levites in place of every firstborn among the Israelites. ¹⁹ From among the Israelites I have given only the Levites to Aaron and his sons to do the work of the people of Israel at the Tent of Meeting and to make atonement for the people of Israel so that there will not be any plague among the Israelites when the Israelites approach the sanctuary.
