Sirach 23:17-19

Revised Standard Version

¹⁷ To a fornicator all bread tastes sweet;
    he will never cease until he dies.
¹⁸ A man who breaks his marriage vows
    says to himself, “Who sees me?
Darkness surrounds me, and the walls hide me,
    and no one sees me. Why should I fear?
The Most High will not take notice of my sins.”
¹⁹ His fear is confined to the eyes of men,
    and he does not realize that the eyes of the Lord
    are ten thousand times brighter than the sun;
they look upon all the ways of men,
    and perceive even the hidden places.
