Sirach 23:17-19

New Revised Standard Version, Anglicised Catholic Edition

¹⁷ To a fornicator all bread is sweet;
    he will never weary until he dies.
¹⁸ One who sins against his marriage bed
    says to himself, ‘Who can see me?
Darkness surrounds me, the walls hide me,
    and no one sees me. Why should I worry?
    The Most High will not remember sins.’
¹⁹ His fear is confined to human eyes
    and he does not realize that the eyes of the Lord
    are ten thousand times brighter than the sun;
they look upon every aspect of human behaviour
    and see into hidden corners.
