Sirach 9:6-8

Revised Standard Version

⁶ Do not give yourself to harlots
    lest you lose your inheritance.
⁷ Do not look around in the streets of a city,
    nor wander about in its deserted sections.
⁸ Turn away your eyes from a shapely woman,
    and do not look intently at beauty belonging to another;
many have been misled by a woman’s beauty,
    and by it passion is kindled like a fire.
