Sirach 23:16–21

16 Two sorts of men multiply sins,

and a third incurs wrath.

The soul heated like a burning fire

will not be quenched until it is consumed;

a man who commits fornication with his near of kin

will never cease until the fire burns him up.

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.

20 Before the universe was created, it was known to him;

so it was also after it was finished.

21 This man will be punished in the streets of the city,

and where he least suspects it, he will be seized.
