'Priests' in the Bible

"A son honors his father and a servant his master. So if I'm a father, where is my honor? And if I'm a master, where is my respect?" says the LORD of the Heavenly Armies to you priests who are despising my name. "But you ask, "How have we despised your name?'

Now this commandment is for you priests:

"But you priests turned aside from the way, and by your teaching you caused many to stumble. You have violated the covenant of Levi," says the LORD of the Heavenly Armies.
