1 Corinthians 10:28-30

Young's Literal Translation

²⁸ and if any one may say to you, `This is a thing sacrificed to an idol,' -- do not eat, because of that one who shewed [it], and of the conscience, for the Lord's [is] the earth and its fulness:

²⁹ and conscience, I say, not of thyself, but of the other, for why [is it] that my liberty is judged by another's conscience?

³⁰ and if I thankfully do partake, why am I evil spoken of, for that for which I give thanks?
