I Timothy 3:2-3, 7

A bishop then must be blameless, the husband of one wife, temperate, sober-minded, of good behavior, hospitable, able to teach; not given to wine, not violent, not greedy for money, but gentle, not quarrelsome, not covetous

Moreover he must have a good testimony among those who are outside, lest he fall into reproach and the snare of the devil.
