Genesis 6:4-5

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 7:3-4

7:3 You must not intermarry with them. Do not give your daughters to their sons or take their daughters for your sons, 7:4 for they will turn your sons away from me to worship other gods. Then the anger of the Lord will erupt against you and he will quickly destroy you.

Deuteronomy 13:6-10

False Prophets in the Family

13:6 Suppose your own full brother, your son, your daughter, your beloved wife, or your closest friend should seduce you secretly and encourage you to go and serve other gods that neither you nor your ancestors have previously known, 13:7 the gods of the surrounding people (whether near you or far from you, from one end of the earth to the other). 13:8 You must not give in to him or even listen to him; do not feel sympathy for him or spare him or cover up for him. 13:9 Instead, you must kill him without fail! Your own hand must be the first to strike him, and then the hands of the whole community. 13:10 You must stone him to death because he tried to entice you away from the Lord your God, who delivered you from the land of Egypt, that place of slavery.

Jude 1:4-5

1:4 For certain men have secretly slipped in among you – men who long ago were marked out for the condemnation I am about to describe – ungodly men who have turned the grace of our God into a license for evil and who deny our only Master and Lord, Jesus Christ.

1:5 Now I desire to remind you (even though you have been fully informed of these facts once for all) that Jesus, having saved the people out of the land of Egypt, later destroyed those who did not believe.

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?”

Malachi 2:15

2:15 No one who has even a small portion of the Spirit in him does this. What did our ancestor do when seeking a child from God? Be attentive, then, to your own spirit, for one should not be disloyal to the wife he took in his youth.

Matthew 14:8-11

14:8 Instructed by her mother, she said, “Give me the head of John the Baptist here on a platter.” 14:9 Although it grieved the king, because of his oath and the dinner guests he commanded it to be given. 14:10 So he sent and had John beheaded in the prison. 14:11 His head was brought on a platter and given to the girl, and she brought it to her mother.
