...holding fast the
faithful word as he has been taught, that he may be able, by
sound doctrine (teaching), both to exhort and convict those who
contradict. — Titus 1:9
But as for you, speak
the things which are proper
for sound doctrine (teaching):
that the older men be sober, reverent, temperate, sound in faith, in
love, in patience; the older women likewise, that they be...
teachers of good things. — Titus 2:1-3
