Passage
And thou--be speaking what doth become the sound teaching;
And thou--be speaking what doth become the sound teaching;
Titus 2:1 And thou--be speaking what doth become the sound teaching;
Titus 2:2 aged men to be temperate, grave, sober, sound in the faith, in the love, in the endurance;
Titus 2:3 aged women, in like manner, in deportment as doth become sacred persons, not false accusers, to much wine not enslaved, of good things teachers,
The verse centers on "thou--be", "speaking", "doth", "become", "sound", and "teaching". It is saying that the verse draws attention to "thou--be" and "speaking", so its meaning should be read from those terms before moving to application.
The next verse adds "aged men to be temperate grave sober...", so "thou--be" and "speaking" should be read forward into that movement. In Titus context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "thou--be" and "speaking" with trust shaped by these words, not by a vague optimism outside the passage.
