Titus 1:5-9 (ESV)
5 This is why I left you in Crete, so that you might put what remained into order, and appoint elders in every town as I directed you— 6 if anyone is above reproach, the husband of one wife, and his children are believers and not open to the charge of debauchery or insubordination. 7 For an overseer, as God's steward, must be above reproach. He must not be arrogant or quick-tempered or a drunkard or violent or greedy for gain, 8 but hospitable, a lover of good, self-controlled, upright, holy, and disciplined. 9 He must hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it.
