Titus 1:7-9

For the bishop must be blameless, as God’s steward; not self-willed, not soon angry, no brawler, no striker, not greedy of filthy lucre; but given to hospitality, a lover of good, sober-minded, just, holy, self-controlled; holding to the faithful word which is according to the teaching, that he may be able both to exhort in the sound doctrine, and to convict the gainsayers.
