Malachi 2:2-4

New Revised Standard Version Catholic Edition

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 on you and I will curse your blessings; indeed I have already cursed them,^[a] because you do not lay it to heart. ³ I will rebuke your offspring, and spread dung on your faces, the dung of your offerings, and I will put you out of my presence.^[b]

⁴ Know, then, that I have sent this command to you, that my covenant with Levi may hold, says the Lord of hosts.
