With respect, Jude had a lot to say about false teachers too:

“Woe to them!  They have taken the way of Cain; they have rushed for profit into Balaam’s error; they have been destroyed in Korah’s rebellion.  These people are… shepherds who feed only themselves…” (Jude 11-12a).

So who were those guys?  In their own way, each was a religious phony.  Cain thought he could make up his own way to worship God, and became a killer (Genesis 4).  Balaam was a false prophet-for-hire, just in it for the money (Numbers 22).  Korah was a Levite who thought he could do a better job of leading Israelite religious services than Moses (Numbers 16).  

In sharp contrast, Jesus said the greatest among His followers should be servant of all (Matthew 23:11), so a minister’s first duty is to feed and care for the congregation, not draw a paycheck or play church.
