Job 31:9-11

31:9 If my heart has been enticed by a woman,

and I have lain in wait at my neighbor’s door,

31:10 then let my wife turn the millstone for another man,

and may other men have sexual relations with her.

31:11 For I would have committed a shameful act,

an iniquity to be judged.

Proverbs 2:16-19

2:16 to deliver you from the adulteress,

from the sexually loose woman who speaks flattering words;

2:17 who leaves the husband from her younger days,

and forgets her marriage covenant made before God.

2:18 For her house sinks down to death,

and her paths lead to the place of the departed spirits.

2:19 None who go in to her will return,

nor will they reach the paths of life.

Proverbs 7:19-23

7:19 For my husband is not at home;

he has gone on a journey of some distance.

7:20 He has taken a bag of money with him;

he will not return until the end of the month.”

7:21 She persuaded him with persuasive words;

with her smooth talk she compelled him.

7:22 Suddenly he went after her

like an ox that goes to the slaughter,

like a stag prancing into a trapper’s snare

7:23 till an arrow pierces his liver

like a bird hurrying into a trap,

and he does not know that it will cost him his life.

Jeremiah 5:8-9

5:8 They are like lusty, well-fed stallions.

Each of them lusts after his neighbor’s wife.

5:9 I will surely punish them for doing such things!” says the Lord.

“I will surely bring retribution on such a nation as this!”

Hebrews 13:4

13:4 Marriage must be honored among all and the marriage bed kept undefiled, for God will judge sexually immoral people and adulterers.
