5:15. Honour and glory is in the word of the wise, but the tongue of the fool is his ruin.
5:16. Be not called a whisperer, and be not taken in thy tongue, and confounded.
5:17. For 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.
5:18. Justify alike the small and the great.
Ecclesiasticus Chapter 6
Of true and false friends: and of the of the fruits of wisdom.
6:1. Instead of a friend become not an enemy to thy neighbour: for an evil man shall inherit reproach and shame, so shall every sinner that is envious and double tongued.
6:2. Extol not thyself in the thoughts of thy soul like a bull: lest thy strength be quashed by folly,
6:3. And it eat up thy leaves, and destroy thy fruit, and thou be left as a dry tree in the wilderness.
