Malachi 2:4

And ye shall know that I have sent this commandment unto
you (See Gill on Malachi 2:1):

that my covenant might be with Levi, saith the Lord of hosts;
not that the ceremonial law might be confirmed and established, on which the Levitical priesthood was founded; for it was the will of God that that should be abolished, because of the weakness and unprofitableness of it; but that the covenant of grace made with Christ, the antitype of Levi, with whom the true Urim and Thummim are, ( Deuteronomy 33:8 ) , who has a more excellent ministry and priesthood than his, might take place, be made manifest, and be exhibited under the Gospel dispensation; of which, and of the person with whom it is, an account is given in the following verses.
