1 Corinthians 10:23 - Matthew Poole's English Annotations on the Holy Bible

All things here must necessarily signify many things, or, at least, (as some think), all those things I have spoken of, to eat meat offered to idols, &c. But if we interpret it in the latter sense, it is not true without limitations; for the apostle had but now determined, that to eat meat offered to idols in the idol's temple, was to have communion with devils. I had rather therefore interpret all by many, as that universal particle must be interpreted in a great multitude of scriptures. So as the sense is: There are many things that are lawful which are not expedient; that is, considered in themselves, under due circumstances, they are lawful, but considered in such and such circumstances, are not so, because they are not for the profit or good, but the hurt and disadvantage, of others. Thus the apostle himself expounds it in the latter clause of the verse, where he saith, they edify not, that is, they tend not to promote the gospel, or the faith and holiness of particular Christians.
