Malachi 2:1-2

New Revised Standard Version, Anglicised

2 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 on you and I will curse your blessings; indeed I have already cursed them,^[a] because you do not lay it to heart.
