Sirach 23:8-10

Revised Standard Version

⁸ The sinner is overtaken through his lips,
    the reviler and the arrogant are tripped by them.
⁹ Do not accustom your mouth to oaths,
    and do not habitually utter the name of the Holy One;
¹⁰ for as a servant who is continually examined under torture
    will not lack bruises,
so also the man who always swears and utters the Name
    will not be cleansed from sin.
