The Greek word “didaktikos”

Limited to 1 Tim. 3:2; 2 Tim. 2:24, the Greek adjective “didaktikos” meant “skillful in teaching” (Silva, 1:710).  Elders (1 Tim. 3:2) and the “Lord’s servant” (2 Tim. 2:24) are to be “apt to teach.”  Part of this aptness seems to involve the refutation of religious error.  Prior “to the NT, this word is attested only in Philo, who applies it not to persons but to virtue ‘acquired by teaching,’ etc., Mut 83” (ibid).
