But as for you, teach what is fitting of sound doctrine:
But speak thou the things which become sound doctrine:
BUT [as for] you, teach what is fitting and becoming to sound (wholesome) doctrine [the character and right living that identify true Christians].
But speak thou the things which befit the sound doctrine:
But you should talk in a way that is consistent with sound teaching.
But you are to speak the things that befit sound doctrine.
