Titus 1:5-9 (NKJV)
[5] For this reason I left you in Crete, that you should set in order the things that are lacking, and appoint elders in every city as I commanded you—
[6] if a man is blameless, the husband of one wife, having faithful children not accused of dissipation or insubordination.
[7] For a bishop must be blameless, as a steward of God, not self-willed, not quick-tempered, not given to wine, not violent, not greedy for money,
[8] but hospitable, a lover of what is good, sober-minded, just, holy, self-controlled,
[9] holding fast the faithful word as he has been taught, that he may be able, by sound doctrine, both to exhort and convict those who contradict.
