A son honors his father, and servants their master. If then I am a father, where is the honor due me? And if I am a master, where is the respect due me? says the Lord of hosts to you, O priests, who despise my name. You say, "How have we despised your name?"
By offering polluted food on my altar. And you say, "How have we polluted it?" By thinking that the Lord's table may be despised.
