1 Enoch 19:1

1 And Uriel said to me: 'Here shall stand the angels who have connected themselves with women, and their spirits assuming many different forms are defiling mankind and shall lead them astray into sacrificing to demons ⌈⌈as gods⌉⌉, (here shall they stand,) till ⌈⌈the day of⌉⌉ the great judgement in which they shall be judged till they are made an end of. 2 And the women also of the angels who went astray shall become sirens.' 3 And I, Enoch, alone saw the vision, the ends of all things: and no man shall see as I have seen.

1 Corinthians 10:20

14 So then, my dear friends, flee from idolatry. 15 I am speaking to thoughtful people. Consider what I say. 16 Is not the cup of blessing that we bless a sharing in the blood of Christ? Is not the bread that we break a sharing in the body of Christ? 17 Because there is one bread, we who are many are one body, for we all share the one bread. 18 Look at the people of Israel. Are not those who eat the sacrifices partners in the altar? 19 Am I saying that idols or food sacrificed to them amount to anything? 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. 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. 22 Or are we trying to provoke the Lord to jealousy? Are we really stronger than he is?
