And Jehovah spake unto Moses, saying,
And thou shalt appoint Aaron and his sons, and they shall keep their priesthood: and the stranger that cometh nigh shall be put to death.
And I, behold, I have taken the Levites from among the children of Israel instead of all the first-born that openeth the womb among the children of Israel; and the Levites shall be mine:
And ye shall know that I have sent this commandment unto you, that my covenant may be with Levi, saith Jehovah of hosts.
