1 Corinthians 10:27-29

King James Version

²⁷ If any of them that believe not bid you to a feast, and ye be disposed to go; whatsoever is set before you, eat, asking no question for conscience sake.

²⁸ But if any man say unto you, this is offered in sacrifice unto idols, eat not for his sake that shewed it, and for conscience sake: for the earth is the Lord's, and the fulness thereof:

²⁹ Conscience, I say, not thine own, but of the other: for why is my liberty judged of another man's conscience?
