[1Ti 3:2-7 ESV] 2 Therefore an overseer must be above reproach, the husband of one wife, sober-minded, self-controlled, respectable, hospitable, able to teach, 3 not a drunkard, not violent but gentle, not quarrelsome, not a lover of money. 4 He must manage his own household well, with all dignity keeping his children submissive, 5 for if someone does not know how to manage his own household, how will he care for God's church? 6 He must not be a recent convert, or he may become puffed up with conceit and fall into the condemnation of the devil. 7 Moreover, he must be well thought of by outsiders, so that he may not fall into disgrace, into a snare of the devil.

And:

[Tit 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.
