Ben Sira 32:9

9 If thou be among great men, make not thyself equal with them; and when ancient men are in place, use not many words.

Ben Sira 32:9 In-Context

7 Speak, young man, if there be need of thee: and yet scarcely when thou art twice asked.
8 Let thy speech be short, comprehending much in few words; be as one that knoweth and yet holdeth his tongue.
9 If thou be among great men, make not thyself equal with them; and when ancient men are in place, use not many words.
10 Before the thunder goeth lightning; and before a shamefaced man shall go favour.
11 Rise up betimes, and be not the last; but get thee home without delay.
