1 Kings 11:8

11:8 He built high places for all his foreign wives so they could burn incense and make sacrifices to their gods.

Genesis 6:2-5

6:2 the sons of God saw that the daughters of humankind were beautiful. Thus they took wives for themselves from any they chose. 6:3 So the Lord said, “My spirit will not remain in humankind indefinitely, since they are mortal. They will remain for 120 more years.”

6:4 The Nephilim were on the earth in those days (and also after this) when the sons of God were having sexual relations with the daughters of humankind, who gave birth to their children. They were the mighty heroes of old, the famous men.

6:5 But the Lord saw that the wickedness of humankind had become great on the earth. Every inclination of the thoughts of their minds was only evil all the time.

Deuteronomy 17:17

17:17 Furthermore, he must not marry many wives lest his affections turn aside, and he must not accumulate much silver and gold.

Nehemiah 13:23-27

13:23 Also in those days I saw the men of Judah who had married women from Ashdod, Ammon, and Moab. 13:24 Half of their children spoke the language of Ashdod (or the language of one of the other peoples mentioned) and were unable to speak the language of Judah. 13:25 So I entered a complaint with them. I called down a curse on them, and I struck some of the men and pulled out their hair. I had them swear by God saying, “You will not marry off your daughters to their sons, and you will not take any of their daughters as wives for your sons or for yourselves! 13:26 Was it not because of things like these that King Solomon of Israel sinned? Among the many nations there was no king like him. He was loved by his God, and God made him king over all Israel. But the foreign wives made even him sin! 13:27 Should we then in your case hear that you do all this great evil, thereby being unfaithful to our God by marrying foreign wives?”

Proverbs 2:16

2:16 to deliver you from the adulteress,

from the sexually loose woman who speaks flattering words;

Proverbs 5:8-20

5:8 Keep yourself far from her,

and do not go near the door of her house,

5:9 lest you give your vigor to others

and your years to a cruel person,

5:10 lest strangers devour your strength,

and your labor benefit another man’s house.

5:11 And at the end of your life you will groan

when your flesh and your body are wasted away.

5:12 And you will say, “How I hated discipline!

My heart spurned reproof!

5:13 For I did not obey my teachers

and I did not heed my instructors.

5:14 I almost came to complete ruin

in the midst of the whole congregation!”

5:15 Drink water from your own cistern

and running water from your own well.

5:16 Should your springs be dispersed outside,

your streams of water in the wide plazas?

5:17 Let them be for yourself alone,

and not for strangers with you.

5:18 May your fountain be blessed,

and may you rejoice in your young wife –

5:19 a loving doe, a graceful deer;

may her breasts satisfy you at all times,

may you be captivated by her love always.

5:20 But why should you be captivated, my son, by an adulteress,

and embrace the bosom of a different woman?

Proverbs 6:24

6:24 by keeping you from the evil woman,

from the smooth tongue of the loose woman.

Proverbs 7:5

7:5 so that they may keep you from the adulterous woman,

from the loose woman who flatters you with her words.

Proverbs 22:14

22:14 The mouth of an adulteress is like a deep pit;

the one against whom the Lord is angry will fall into it.

Proverbs 23:33

23:33 Your eyes will see strange things,

and your mind will speak perverse things.
