And LORD spoke to Moses, saying,
And thou shall appoint Aaron and his sons, and they shall keep their priesthood. And the stranger who comes near shall be put to death.
And I, behold, I have taken the Levites from among the sons of Israel instead of all the first-born who opens the womb among the sons of Israel. And the Levites shall be mine,
And ye shall know that I have sent this commandment to you, that my covenant may be with Levi, says LORD of hosts.
