“But if any man say vnto you, This is offered in sacrifice vnto idoles, eate not for his sake that shewed it, and for conscience sake. The earth is the Lords, and the fulnesse thereof.”
1611 King James Version (KJV)
10:28 For his sake that showed thee, and for conscience' sake - That is, for the sake of his weak conscience, lest it should be wounded.
1Co 10:28 But if any man shall say unto you, etc. If some one points out that a part is from an idol's sacrifice, then it is not to be eaten; not because the food is sinful, but because the conscience of others might be offended.
