Behold, I have taken the Levites from among the Israelites instead of every firstborn who opens the womb among the Israelites; and the Levites shall be Mine,
And you shall know, recognize, and understand that I have sent this [new] decree to you priests, to be My [new] covenant with Levi [the priestly tribe], says the Lord of hosts.
