Malachi Ch.2 Vv.1-4
And now, O ye priests, this commandment is for you.
If ye will not hear, and if ye will not lay it to heart, to give glory unto my name, saith the LORD of hosts, I will even send a curse upon you, and I will curse your blessings: yea, I have cursed them already, because ye do not lay it to heart.
Behold, I will corrupt your seed, and spread dung upon your faces, even the dung of your solemn feasts; and one shall take you away with it.
And ye shall know that I have sent this commandment unto you, that my covenant might be with Levi, saith the LORD of hosts.
