Sirach 32:9

9 When you are among the more influential, don't presume authority; and where elders are present, don't talk idly about many things.

Sirach 32:9 In-Context

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.

10 Lightning comes before thunder, and good favor walks in front of a modest person.

11 Rise up to leave in time, and don't be the last person out; go back to your own home, and don't miss your work the next day.
