Thematic Bible: What cannot be partaken together

What say I then? that a thing sacrificed to idols is anything, or that an idol is anything? But I say , that the things which the Gentiles sacrifice, they sacrifice to demons, and not to God: and I would not that ye should have communion with demons. Ye cannot drink the cup of the Lord, and the cup of demons: ye cannot partake of the table of the Lord, and of the table of demons.
