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 meeting, 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 near unto the sanctuary.

And I, behold, I have taken your brethren the Levites from among the children of Israel: to you they are given as a gift for the LORD, to do the service of the tabernacle of meeting.

Therefore you and your sons with you shall keep your priest's office for everything at the altar, and within the veil; and you shall serve: I have given your priest's office unto you as a gift for service: and the stranger that comes near shall be put to death.

And this is yours; the heave offering of their gift, with all the wave offerings of the children of Israel: I have given them unto you, and to your sons and to your daughters with you, by a statute forever: everyone that is clean in your house shall eat of it.
