Malachi 1:6-7

6 A son honors his father, and a servant his master: if then I be a father, where is my honor? and if I be a master, where is my fear? said the LORD of hosts to you, O priests, that despise my name. And you say, Wherein have we despised your name?

7 You offer polluted bread on my altar; and you say, Wherein have we polluted you? In that you say, The table of the LORD is contemptible.
