King James Version
And I have given the Levites as a gift to Aaron and to his sons from among the children of Israel, to do the service of the children of Israel in the tabernacle of the congregation, and to make an atonement for the children of Israel: that there be no plague among the children of Israel, when the children of Israel come nigh unto the sanctuary.New International Version
Of all the Israelites, I have given the Levites as gifts to Aaron and his sons to do the work at the Tent of Meeting on behalf of the Israelites and to make atonement for them so that no plague will strike the Israelites when they go near the sanctuary."Catholic Public Domain Version
And I have delivered them as a gift to Aaron and his sons, from the midst of the people, in order to serve me, for Israel, in the tabernacle of the covenant, and in order to pray for them, lest there be a scourge among the people, if they were to dare to approach to my Sanctuary.
