Numbers 8:19
Brenton's English Septuagint · Berean Standard Bible
And I gave the Levites presented as a gift to Aaron and his sons out of the midst of the children of Israel, to do the service of the children of Israel in the tabernacle of witness, and to make atonement for the children of Israel: thus there shall be none among the sons of Israel to draw nigh to the holy things.
And I have given the Levites as a gift to Aaron and his sons from among the Israelites, to perform the service for the Israelites at the Tent of Meeting and to make atonement on their behalf, so that no plague will come against the Israelites when they approach the sanctuary.”
