Malachi 2:1-2

Darby Translation

2 And now, ye priests, this commandment is for you.

² If ye do not hear, and if ye do not lay [it] to heart, to give glory unto my name, saith Jehovah of hosts, I will even send the curse among you, and I will curse your blessings: yea, I have already cursed them, because ye do not lay [it] to heart.
