YLT(i)
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?
31 Whether, then, ye eat, or drink, or do anything, do all to the glory of God;
