Sirach 19:9 CPDV

⁷  You should not repeat a wicked and harsh word, and then you will not be diminished.

⁸  Do not reveal your mind to friend or foe. And if there is a sin within you, do not disclose it.

⁹  For he will listen to you and watch you, and while pretending to defend your sin, he will despise you, and so he will be whenever he is with you.

¹⁰  Have you heard a word against your neighbor? Let it die within you, trusting that it will not burst forth from you.

¹¹  Before the face of a word, a foolish man labors, like a woman groaning as she gives birth to a child.
