⁴¹ And thou shalt take the Levites to me for all the firstborn of the children of Israel, I am the Lord: and their cattle for all the firstborn of the cattle of the children of Israel:

¹⁰ To Aaron and to his sons, to whom they are delivered by the children of Israel. But thou shalt appoint Aaron and his sons over the service of priesthood. The stranger that approacheth to minister, shall be put to death.
