1 Corinthians 8:10-12

Darby Translation

¹⁰ For if any one see thee, who hast knowledge, sitting at table in an idol-house, shall not his conscience, he being weak, be emboldened to eat the things sacrificed to the idol?

¹¹ and the weak [one], the brother for whose sake Christ died, will perish through thy knowledge.

¹² Now, thus sinning against the brethren, and wounding their weak conscience, ye sin against Christ.
