15After that, the Levites will go in to do whatever has to be done in the Tent of meeting; you are to make them clean and give them as a wave offering.
16For they have been given to me from among the children of Israel; in place of every mother's first son, the first to come to birth in Israel, I have taken them for myself.
17For every mother's first son among the children of Israel is mine, the first male birth of man or beast: on the day when I sent death on all the first sons in the land of Egypt, I made them mine.
18And in place of the first sons among the children of Israel, I have taken the Levites.
19And I have given them to Aaron and to his sons, from among the children of Israel, to undertake for them all the work of the Tent of meeting, and to take away sin from the children of Israel so that no evil may come on them when they come near the holy place.
20All these things Moses and Aaron and the children of Israel did to the Levites; as the Lord gave orders to Moses about the Levites, so the children of Israel did.
21And the Levites were made clean from sin, and their clothing was washed, and Aaron gave them for a wave offering before the Lord; and Aaron took away their sin and made them clean.
