1 Corinthians 10:18-20

Amplified Bible

¹⁸ Consider the people of Israel; are those who eat the sacrifices not partners of the altar [united in their worship of the same God]? [Indeed they are.]^{(A) 19} What do I mean then? That a thing offered to idols is anything [special or changed simply because it is offered], or that an idol is anything? ²⁰ On the contrary, the things which the Gentiles (pagans) sacrifice, they sacrifice to demons [in effect], and not to God; and I do not want you to become partners with demons [by eating at feasts in pagan temples].^(B)
