'Bishop' in the Bible

This is a true saying, If a man desire the office of a bishop, he desireth a good work.

A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;

For a bishop must be blameless, as the steward of God; not selfwilled, not soon angry, not given to wine, no striker, not given to filthy lucre;

For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls.
