Wisdom of Ben Sira 20:6-8

New Catholic Bible

⁶ One man keeps silent because he has nothing to say,
    while another keeps quiet because he knows when to speak.
⁷ A wise man remains silent until the right moment,
    but a boasting fool never seems aware of the proper time.
⁸ The one who talks too much is detested,
    and the one who pretends to be an authority is hated.
[How good it is to show repentance when you are rebuked,
    for you will thereby avoid deliberate sin.]^[a]
