Malachi 2:4 - Matthew Poole's English Annotations on the Holy Bible

And ye, O priests, shall know, by sense and feeling, by woeful experience; or, know ye, i.e. but what I speak now, and will do among you. I have sent this commandment; admonition, reproof, and exhortation, to look more carefully for the future, that you do not dishonour me, and make mine altar and sacrifices contemptible; but repent of what is past, and for time to come amend all; this I call for at your hands. That my covenant might be with Levi; that you do not null the covenant of priesthood made with Levi, and which I would have continued in his posterity, in you, and yours after you, which I would not have your sins and high provocations should abrogate; but if you will not thus confirm, settle, and keep Levi's covenant among you, I will make it firm as to what is on my part to be done herein, to punish the violators of it. Saith the Lord of hosts; God Almighty, Lord of hosts, hath spoken this, and will do it.
