Sirach 6:4

4 If you have a bad soul, it will destroy you; it will make you a joke to your enemies.

Sirach 6:4 In-Context

2 Don't be enamored of your own intelligence lest your strength be taken captive like a bull.

3 You will devour your leaves, destroy your fruit, and leave yourself like a withered tree.

4 If you have a bad soul, it will destroy you; it will make you a joke to your enemies.

5 Pleasant speech gains more friends for itself, and a sweet-speaking tongue will multiply pleasant exchanges.

6 Let those who are at peace with you be many, but let only one in a thousand be your advisor.
