1 Timothy 3:2-3

3:2 The overseer then must be above reproach, the husband of one wife, temperate, self-controlled, respectable, hospitable, an able teacher, 3:3 not a drunkard, not violent, but gentle, not contentious, free from the love of money.

Titus 1:9

1:9 He must hold firmly to the faithful message as it has been taught, so that he will be able to give exhortation in such healthy teaching and correct those who speak against it.
