Let no one be found among you who sacrifices his son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft,
or casts spells, or who is a medium or spiritist or who consults the dead.
Anyone who does these things is detestable to the LORD, and because of these detestable practices the LORD your God will drive out those nations before you.
Deuteronomy Chapter 18: Verses 10 - 12
When men tell you to consult mediums and spiritists, who whisper and mutter, should not a people inquire of their God? Why consult the dead on behalf of the living?
To the law and to the testimony! If they do not speak according to this word, they have no light of dawn.
Distressed and hungry, they will roam through the land; when they are famished, they will become enraged and, looking upward, will curse their king and their God.
Then they will look toward the earth and see only distress and darkness and fearful gloom, and they will be thrust into utter darkness.
Isaiah Chapter 8: Verses 19 - 22
"This is what the LORD says, your Redeemer, who formed you in the womb: I am the LORD, who has made all things, who alone stretched out the heavens, who spread out the earth by myself,
who foils the signs of false prophets and makes fools of diviners, who overthrows the learning of the wise and turns it into nonsense,
Isaiah Chapter 44: Verses 24 - 25
All the counsel you have received has only worn you out! Let your astrologers come forward, those stargazers who make predictions month by month, let them save you from what is coming upon you.
Surely they are like stubble; the fire will burn them up. They cannot even save themselves from the power of the flame. Here are no coals to warm anyone; here is no fire to sit by.
Isaiah Chapter 47: Verses 13 - 14
So do not listen to your prophets, your diviners, your interpreters of dreams, your mediums or your sorcerers who tell you, 'You will not serve the king of Babylon.'
They prophesy lies to you that will only serve to remove you far from your lands; I will banish you and you will perish.
Jeremiah Chapter 27: Verses 9 - 10
idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions
and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
Galatians Chapter 5: Verses 20 - 21
The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons.
Such teachings come through hypocritical liars, whose consciences have been seared as with a hot iron.
1 Timothy Chapter 4: Verses 1 - 2
