Sirach 9:8-10

New Revised Standard Version, Anglicised Catholic Edition

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.

¹⁰ Do not abandon old friends,
    for new ones cannot equal them.
A new friend is like new wine;
    when it has aged, you can drink it with pleasure.
