Numbers 8:18-20

New International Reader's Version

¹⁸ And I have taken the Levites in place of all the sons born first in Israel. ¹⁹ I have given the Levites as gifts to Aaron and his sons. I have taken them from among all the Israelites. I have appointed them to do the work at the tent of meeting. They will do it in place of the Israelites. That is how they will keep the Israelites from being guilty when they go near the sacred tent. Then no plague will strike the Israelites when they go near the tent.”

²⁰ So Moses and Aaron and all the Israelites did with the Levites just as the Lord had commanded Moses.
