God excoriates the priests for neglecting their priestly covenant. Speak truth, respect God, respect your mission, teach life, teach peace and live a straight and honest life. When a religious leader exhibits these qualities, he leads the people back to God. But the priests are not following this path, they disrespect God, they teach a "Torah" that is dishonest, one that is used for their own personal advancement. Such a "leader" brings shame and disrespect.
