Sirach 23:8-10

New Revised Standard Version, Anglicised Catholic Edition

⁸ Sinners are overtaken through their lips;
    by them the reviler and the arrogant are tripped up.
⁹ Do not accustom your mouth to oaths,
    nor habitually utter the name of the Holy One;
¹⁰ for as a servant who is constantly under scrutiny
    will not lack bruises,
so also the person who always swears and utters the Name
    will never be cleansed^[a] from sin.
