1 Corinthians 10:25,26 - Joseph Benson’s Commentary on the Old and New Testaments

The apostle now applies this principle to the point in question; and on the ground of it, gives the following rules concerning meats. Whatsoever is sold in the shambles Though it were offered to idols before, yet being now set openly to sale, the idol is no more honoured therewith, and it is common meat; that you may buy, and eat it in private, either in a friend's house or your own, asking no question Whether it has been offered in sacrifice to an idol or not; for conscience' sake With a view to satisfy your conscience respecting the lawfulness of eating it. Or the expression, for conscience' sake, may mean, lest any needless scruple should arise, either in your own or your brother's conscience, so that you could not eat of it freely, without doubting in yourself, or giving offence to your brother. For the earth is the Lord's, as the psalmist has expressed it, Psalms 24:1, and the fulness thereof All creatures therein, which were made for man's use, and are given us freely to enjoy in Christ, 1Ti 4:4; 1 Timothy 6:17. And no demon hath any power or dominion over them. “By this argument the apostle showed the Corinthians that their knowledge and faith, as Christians, ought to prevent them from asking any questions concerning their food, which might lead the heathen to think that they acknowledged the power of their deities, either to give or to withhold any part of the fulness of the earth from the worshippers of the true God.”
