Ben Sira 20:7

7 A wise person will not speak until the right moment, but a bragging fool doesn't know when that time is.

Ben Sira 20:7 In-Context

5 Some people are thought to be wise because they don't talk much; others are disliked because they talk too much.
6 Some people keep quiet because they don't have anything to say; others keep quiet because they know the right time to speak.
7 A wise person will not speak until the right moment, but a bragging fool doesn't know when that time is.
8 No one can stand a person who talks too long and will not give others a chance to speak.
9 Bad luck can sometimes lead to success, and a stroke of good luck can sometimes lead to loss.
