Ben Sira 32:8

8 Let thy speech be short, comprehending much in few words; be as one that knoweth and yet holdeth his tongue.

Ben Sira 32:8 In-Context

6 As a signet of an emerald set in a work of gold, so is the melody of musick with pleasant wine.
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.
