Sirach 5:15LXX

13Be meek to hear the word, that thou mayst understand: and return a true answer with wisdom.

14If thou have understanding, answer thy neighbour: but if not, let thy hand be upon thy mouth, lest thou be surprised in an unskillful word, and be confounded.

15Honour and glory is in the word of the wise, but the tongue of the fool is his ruin.

16Be not called a whisperer, and be not taken in thy tongue, and confounded.

17For confusion and repentance is upon a thief, and an evil mark of disgrace upon the double tongued, but to the whisperer hatred, and enmity, and reproach.
