Titus 1:5-9

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: any man who is blameless, the husband of one wife, having faithful children who are not accused of being wild or unruly. For an overseer must be blameless, as a steward of God, not self-willed, not easily angered, not given to drunkenness, not violent, not greedy for dishonest gain, but hospitable, a lover of what is good, self-controlled, just, holy, temperate, holding firmly the trustworthy word that is in accordance with the teaching, that he may be able both to exhort with sound doctrine and to convince those who oppose it.
