Titus 1:5-9

For this reason I left you [behind] in Crete, that you might set right what was defective and finish what was left undone, and that you might appoint elders and set them over the churches (assemblies) in every city as I directed you. [These elders should be] men who are of unquestionable integrity and are irreproachable, the husband of [but] one wife, whose children are [well trained and are] believers, not open to the accusation of being loose in morals and conduct or unruly and disorderly. For the bishop (an overseer) as God's steward must be blameless, not self-willed or arrogant or presumptuous; he must not be quick-tempered or given to drink or pugnacious (brawling, violent); he must not be grasping and greedy for filthy lucre (financial gain); But he must be hospitable (loving and a friend to believers, especially to strangers and foreigners); [he must be] a lover of goodness [of good people and good things], sober-minded (sensible, discreet), upright and fair-minded, a devout man and religiously correct, temperate and keeping himself in hand. He must hold fast to the sure and trustworthy Word of God as he was taught it, so that he may be able both to give stimulating instruction and encouragement in sound (wholesome) doctrine and to refute and convict those who contradict and oppose it [showing the wayward their error].
