Sirach 9:1-9

New Revised Standard Version Catholic Edition

9 Do not be jealous of the wife of your bosom,
    or you will teach her an evil lesson to your own hurt.
² Do not give yourself to a woman
    and let her trample down your strength.
³ Do not go near a loose woman,
    or you will fall into her snares.
⁴ Do not dally with a singing girl,
    or you will be caught by her tricks.
⁵ Do not look intently at a virgin,
    or you may stumble and incur penalties for her.
⁶ Do not give yourself to prostitutes,
    or you may lose your inheritance.
⁷ Do not look around in the streets of a city,
    or wander about in its deserted sections.
⁸ Turn away your eyes from a shapely woman,
    and do not gaze at beauty belonging to another;
many have been seduced by a woman’s beauty,
    and by it passion is kindled like a fire.
⁹ Never dine with another man’s wife,
    or revel with her at wine;
or your heart may turn aside to her,
    and in blood^[a] you may be plunged into destruction.
