Wisdom of Ben Sira 20:4-6

New Catholic Bible

⁴ Like a eunuch lusting to ravage a maiden
    is the person who does what is right out of obligation.^[a]
5 One man is silent and considered to be wise,
    while another incurs hatred for talking too much.
⁶ One man keeps silent because he has nothing to say,
    while another keeps quiet because he knows when to speak.
