Sirach 6:1-3

Douay-Rheims 1899 American Edition

6 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.

² Extol not thyself in the thoughts of thy soul like a bull: lest thy strength be quashed by folly,

³ And it eat up thy leaves, and destroy thy fruit: and thou be left as a dry tree in the wilderness.
