Sirach 23:16-17

Revised Standard Version

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^[a]
    will never cease until the fire burns him up.
¹⁷ To a fornicator all bread tastes sweet;
    he will never cease until he dies.
