1-corinthians 8:10

If any man see thee which hast knowledge - Of the true God, and who art reputed for thy skill in Divine things.

Sit at meat in the idol's temple - Is it not strange that any professing the knowledge of the true God should even enter one of those temples? And is it not more surprising that any Christian should be found to feast there? But by all this we may see that the boasted knowledge of the Corinthians had very little depth in things purely spiritual.

There are many curious thin-spun theories in the rabbinical writings concerning entering idol temples, and eating there, and even worshipping there, providing the mind be towards the true God. Dr. Lightfoot produces several quotations to prove this. Perhaps the man of knowledge mentioned by the apostle was one of those who, possessing a convenient conscience, could accommodate himself to all circumstances; be a heathen without and a Christian within, and vice versa, as circumstances might require.

Be emboldened to eat - Οικοδομηθησεται, Be built up - be confirmed and established in that opinion which before he doubtingly held, that on seeing You eat he may be led to think there is no harm in feasting in an idol temple, nor in eating things offered to idols.

For if any man - Any Christian brother who is ignorant, or anyone who might otherwise become a Christian.

Which hast knowledge - Who are fully informed in regard to the real nature of idol worship. You will be looked up to as an example. You will be presumed to be partaking of this feast in honor of the idol. You will thus encourage him, and he will partake of it with a conscientious regard to the idol.

Sit at meat - Sitting down to an entertainment in the temple of the idol. Feasts were often celebrated, as they are now among the pagan, in honor of idols. Those entertainments were either in the temple of the idol, or at the house of him who gave it.

Shall not the conscience of him which is weak - Of the man who is not fully informed, or who still regards the idol with superstitious feelings; see 1 Corinthians 8:7.

Be emboldened - Margin, "Edified" οἰκοδομηθήσεται oikodomēthēsetai. Confirmed; established. So the word "edify" is commonly used in the New Testament; Acts 9:31; Romans 14:19; Ephesians 4:12; 1 Thessalonians 5:11. The sense here is, "Before this he had a superstitious regard for idols. He had the remains of his former feelings and opinions. But he was not established in the belief that an idol was anything; and his superstitious feelings were fast giving way to the better Christian doctrine that they were nothing. But now, by your example, he will be fully confirmed in the belief that an idol is to be regarded with respect and homage. He will see you in the very temple, partaking of a feast in honor of the idol; and he will infer not only that it is right, but that it is a matter of conscience with you, and will follow your example."

8:10 For if any one see thee who hast knowledge - Whom he believes to have more knowledge than himself, and who really hast this knowledge, that an idol is nothing - sitting down to an entertainment in an idol temple. The heathens frequently made entertainments in their temples, on what hath been sacrificed to their idols. Will not the conscience of him that is weak - Scrupulous. Be encouraged - By thy example. To eat - Thoughwith a doubting conscience.
