1 Corinthians 10:19-21

10:19 Am I saying that idols or food sacrificed to them amount to anything? 10:20 No, I mean that what the pagans sacrifice is to demons and not to God. I do not want you to be partners with demons. 10:21 You cannot drink the cup of the Lord and the cup of demons. You cannot take part in the table of the Lord and the table of demons.
