1 Timothy 3:4

² A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;

³ Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous;

One that ruleth well his own house, having his children in subjection with all gravity;

⁵ (For if a man know not how to rule his own house, how shall he take care of the church of God?)

⁶ Not a novice, lest being lifted up with pride he fall into the condemnation of the devil.

Do read the surrounding verses too, because the context often says more than a single verse.
