Sirach 23:8-10

Douay-Rheims 1899 American Edition

⁸ A sinner is caught in his own vanity, and the proud and the evil speakers shall fall thereby.

⁹ Let not thy mouth be accustomed to swearing: for in it there are many falls.

¹⁰ And let not the naming of God be usual in thy mouth, and meddle not with the names of saints, for thou shalt not escape free from them.
