In context
Before · 1 Corinthians 10:19–20
19What am I saying then? That a thing sacrificed to idols is anything, or that an idol is anything? 20But I say that the things which the Gentiles sacrifice, they sacrifice to demons and not to God, and I don’t desire that you would have fellowship with demons.
21You can’t both drink the cup of the Lord and the cup of demons. You can’t both partake of the table of the Lord and of the table of demons.
