Malachi 1:6-7, 12
6 A son honoureth his father, and a servant his master: if then I be a father, where is mine honour? and if I be a master, where is my fear? saith the LORD of hosts unto you, O priests, that despise my name. And ye say, Wherein have we despised thy name?
7 Ye offer polluted bread upon mine altar; and ye say, Wherein have we polluted thee? In that ye say, The table of the LORD is contemptible.
12 But ye have profaned it, in that ye say, The table of the LORD is polluted; and the fruit thereof, even his meat, is contemptible.
Malachi 2:2
2 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.
