A man who is appointed to be an overseer should be free from accusation, exemplary both in his person and in his family life, hospitable, balanced, and self-controlled; he must properly represent the truth in his teaching and thus be able to exhort and to reprove those who contradict (1:6-9)
... Aged men are encouraged to be exemplary in moderation, seriousness, soundness of mind, faith, love, and endurance (2:1, 2)
