Sirach 20:6-8

New Revised Standard Version, Anglicised

⁶ Some people keep silent because they have nothing to say,
    while others keep silent because they know when to speak.
⁷ The wise remain silent until the right moment,
    but a boasting fool misses the right moment.
⁸ Whoever talks too much is detested,
    and whoever pretends to authority is hated.^[a]
