1 Corinthians 10
18 Ref Consider Israel after the flesh. Don't those who eat the sacrifices have communion with the altar?
19 Ref What am I saying then? That a thing sacrificed to idols is anything, or that an idol is anything?
20 Ref But 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 communion with demons.
