Sirach 32:7-9

Common English Bible

⁷ Speak, you who are young,
if it’s necessary,
    but only twice,
    and only if you are asked.
⁸ Sum up what you have to say;
much can be said in few words.
Be like one who knows
but who can keep silent.
⁹ When you are among the more influential, don’t presume authority;
    and where elders are present,
    don’t talk idly about many things.
