Deuteronomy 18:10-12

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.

Leviticus 18:26b, 31
Do not practice divination or sorcery. . . . ‘Do not turn to mediums or seek out spiritists,  for you will be defiled by them. I am the LORD your God.

Ezekiel 28:11-17

The word of the LORD came to me: “Son of man, take up a lament concerning the king of Tyre and say to him: ‘This is what the Sovereign LORD says: “ ‘You were the model of perfection, full of wisdom and perfect in beauty. You were in Eden, the garden of God; every precious stone adorned you: ruby, topaz and emerald, chrysolite, onyx and jasper, sapphire, turquoise and beryl. Your settings and mountings were made of gold; on the day you were created they were prepared. You were anointed as a guardian cherub, for so I ordained you. You were on the holy mount of God; you walked among the fiery stones. You were blameless in your ways from the day you were created till wickedness was found in you. Through your widespread trade you were filled with violence, and you sinned.

So I drove you in disgrace from the mount of God, and I expelled you, O guardian cherub, from among the fiery stones. Your heart became proud on account of your beauty, and you corrupted your wisdom because of your splendor. So I threw you to the earth; I made a spectacle of you before kings.

John 8:44

You belong to your father, the devil, and you want to carry out your father’s desire. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.

Acts 19: 18-20

Many of those who believed now came and openly confessed their evil deeds. A number who had practiced sorcery brought their scrolls together and burned them publicly. When they calculated the value of the scrolls, the total came to fifty thousand drachmas. In this way the word of the Lord spread widely and grew in power.

1 Corinthians 10:20
No, but the sacrifices of pagans are offered to demons, not to God, and I do not want you to be participants with demons.

2 Corinthians4:4
The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel of the glory of Christ, who is the image of God.

2 Corinthians 11:13-15

For such men are false apostles, deceitful workmen, masquerading as apostles of Christ. And no wonder, for Satan himself masquerades as an angel of light. It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will be what their actions deserve.
