Apparently adultery is a really, really, really bad idea. Allow me to give you a sampling:
16 Wisdom will save you also from the adulterous woman,
from the wayward woman with her seductive words,
17 who has left the partner of her youth
and ignored the covenant she made before God.
18 Surely her house leads down to death
and her paths to the spirits of the dead.
19 None who go to her return
or attain the paths of life.
5 Her feet go down to death;
her steps lead straight to the grave.
6 She gives no thought to the way of life;
her paths wander aimlessly, but she does not know it.
8 Keep to a path far from her,
do not go near the door of her house,
9 lest you lose your honor to others
and your dignity to one who is cruel,
10 lest strangers feast on your wealth
and your toil enrich the house of another.
11 At the end of your life you will groan,
when your flesh and body are spent.
26 For a prostitute can be had for a loaf of bread,
but another man’s wife preys on your very life.
27 Can a man scoop fire into his lap
without his clothes being burned?
28 Can a man walk on hot coals
without his feet being scorched?
29 So is he who sleeps with another man’s wife;
no one who touches her will go unpunished.
32 But a man who commits adultery has no sense;
whoever does so destroys himself.
33 Blows and disgrace are his lot,
and his shame will never be wiped away.
25 Do not let your heart turn to [the adulterous woman’s] ways
or stray into her paths.
26 Many are the victims she has brought down;
her slain are a mighty throng.
27 Her house is a highway to the grave,
leading down to the chambers of death.
It appears to say, if I can boil it down, is that if you do this, you’re screwed. And this was written by King David, a guy who had a dude killed so he could sleep with said dude’s wife. So I’m thinking he would know…
