Ben Sira 23:17

17 Let not thy mouth be accustomed to indiscreet speech: for therein is the word of sin.

Ben Sira 23:17 In-Context

15 There is also another speech opposite to death, let it not be found in the inheritance of Jacob.
16 For from the merciful all these things shall be taken away, and they shall not wallow in sins.
17 Let not thy mouth be accustomed to indiscreet speech: for therein is the word of sin.
18 Remember thy father and thy mother, for thou sittest is the midst of great men:
19 Lest God forget thee in their sight, and thou, by thy daily custom, be infatuated and suffer reproach: and wish that thou hadst not been born, and curse the day of thy nativity
