Titus 1:7-9

The overseer, since he serves God’s household, must be someone of blameless character and not be opinionated or short-tempered. He must not be a drunkard or violent or greedy. Instead he should be one who is known for his hospitality and a lover of goodness. He should be recognized as one who is fair-minded, pure-hearted, and self-controlled. He must have a firm grasp of the trustworthy message that he has been taught. This will enable him to both encourage others with healthy teachings and provide convincing answers to those who oppose his message.
