Malachi 2:1-7
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.My covenant was with him of life and peace; and I gave them to him[ for] the fear wherewith he feared me, and was afraid before my name.The law of truth was in his mouth, and iniquity was not found in his lips: he walked with me in peace and equity, and did turn many away from iniquity.For the priest’s lips should keep knowledge, and they should seek the law at his mouth: for he[ is] the messenger of the LORD of hosts.
