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, apttoteach; Not giventowine, nostriker, not greedy of filthy lucre; but patient, not a brawler, not covetous.

-Bible (NewTestament)
  Timothy 3:1^3.
