Ben Sira 9:8

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.

Ben Sira 9:8 In-Context

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.
9 Never dine with another man's wife, nor revel with her at wine; lest your heart turn aside to her, and in blood you be plunged into destruction.
10 Forsake not an old friend, for a new one does not compare with him. A new friend is like new wine; when it has aged you will drink it with pleasure.
