Sirach 20:1-6

1 There is a reproof that is not comely: again, some man holdeth his tongue, and he is wise.
2 It is much better to reprove, than to be angry secretly: and he that confesseth his fault shall be preserved from hurt.
3 How good is it, when thou art reproved, to shew repentance! for so shalt thou escape wilful sin.
4 As is the lust of an eunuch to deflower a virgin; so is he that executeth judgment with violence.
5 There is one that keepeth silence, and is found wise: and another by much babbling becometh hateful.
6 Some man holdeth his tongue, because he hath not to answer: and some keepeth silence, knowing his time.
