Matthew Poole and continuators on 1 Corinthians 10:29

29 Conscience, I say, not thine own, but of the others : for why is my liberty judged by another mans conscience? .

By reason of what we had, v. 28. (where the Apostle forbad eating these meats, in case any of the Feast told them they had been offered to Idols, both for his sake that told him so; and also for conscience sake) it is most reasonable to interpret those words, not thine own in this verse, not thine own only, there being frequent instances in Scripture, where the Negative Particle must be so restrained, as Ioh. 4.42. Chap. 6.27, 38.

For why should my practice in a thing, wherein I have a liberty, be censured or condemned by the conscience of another, he being perswaded, that what I do and judge that I have a liberty to do, and may do lawfully, is done by me sinfully, and I by him accounted a transgressor for it; so as, though I do a thing that is honest, yet it is not honest in the sight of all men, or of good report, whereas Christians are obliged, Rom. 12.17. to provide things honest in the sight of all men, not in his own sight meerly, and to do those things that are lovely and of good report Phil. 3.8.
