When you come into the land which the Lord your God is giving you, you shall not learn to follow the abominations of those nations. There shall not be found among you anyone who makes his son or his daughter pass through the fire, or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead. For all who do these things are an abomination to the Lord, and because of these abominations the Lord your God drives them out from before you. You shall be blameless before the Lord your God. For these nations which you will dispossess listened to soothsayers and diviners; but as for you, the Lord your God has not appointed such for you. (Deuteronomy 18:9-14)

And the person who turns to mediums and familiar spirits, to prostitute himself with them, I will set My face against that person and cut him off from his people. Consecrate yourselves therefore, and be holy, for I am the Lord your God. (Leviticus 20:6-7)

A man or a woman who is a medium, or who has familiar spirits, shall surely be put to death; they shall stone them with stones. Their blood shall be upon them. (Leviticus 20:27)

But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death. (Revelation 21:8)

Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness, idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God. (Galatians 5:19-21)

And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God. (John 3:19-21)

The night is far spent, the day is at hand. Therefore let us cast off the works of darkness, and let us put on the armor of light. (Romans 13:12)

For you were once darkness, but now you are light in the Lord. Walk as children of light (for the fruit of the Spirit is in all goodness, righteousness, and truth), finding out what is acceptable to the Lord. And have no fellowship with the unfruitful works of darkness, but rather expose them. (Ephesians 5:8-11)

For your obedience has become known to all. Therefore I am glad on your behalf; but I want you to be wise in what is good, and simple concerning evil. (Romans 16:19)

Abstain from every form of evil. (1 Thessalonians 5:22)

This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all. If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth. But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin. (1 John 1:5-7)

Then Jesus spoke to them again, saying, "I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life." (John 8:12)
