Sirach 21:25-27

Wycliffe Bible

²⁵ The lips of unprudent men shall tell fond things [or follies]; but the words of prudent men shall be weighed in a balance.

²⁶ The heart of fools is in their mouth; and the mouth of wise men is in their heart.

²⁷ When a wicked man curseth the devil, he curseth his own soul. [When the unpious curseth the devil, he curseth his own soul.]
