'Evil Spirits' in the Bible

[Certainly not!] But I am saying that the Gentile sacrifices are [really] offered to evil spirits and not to God. And I do not want you to have fellowship with evil spirits.

You cannot drink [both] the cup of the Lord and the cup of evil spirits [i.e., and still be acceptable to God]. You cannot share in [both] the Lord's table and the table of evil spirits [and still be acceptable to God].
