Titus 1:5-9

For this reason I left you behind in Crete, so that you would set right what remains unfinished, and appoint elders in every city as I directed you, namely, a man of unquestionable integrity, the husband of one wife, having children who believe, not accused of being immoral or rebellious. For the overseer, as God’s steward, must be blameless, not self-willed, not quick-tempered, not addicted to wine, not violent, not greedy for dishonest gain [but financially ethical]. And he must be hospitable [to believers, as well as strangers], a lover of what is good, sensible (upright), fair, devout, self-disciplined [above reproach—whether in public or in private]. He must hold firmly to the trustworthy word [of God] as it was taught to him, so that he will be able both to give accurate instruction in sound [reliable, error-free] doctrine and to refute those who contradict [it by explaining their error].
