Malachi 1:14–2:2
14 Cursed be the cheat who has a male in his flock, and vows it, and yet sacrifices to the Lord what is blemished; for I am a great King, says the Lord of hosts, and my name is feared among the nations.
1 “And now, O priests, this command is for you. 2 If you will not listen, if you will not lay it to heart to give glory to my name, says the Lord of hosts, then I will send the curse upon you and I will curse your blessings; indeed I have already cursed them, because you do not lay it to heart.
