Wisdom of Ben Sira 9:5-7

New Catholic Bible

⁵ Do not harbor lustful thoughts against a virgin,
    or you may incur punishment on account of her.
⁶ Do not give yourself to prostitutes,
    lest you suffer the loss of your inheritance.
⁷ Do not let your gaze stray through the streets of a city,
    or wander around its deserted areas.
