1 Corinthians 8:11 in the King James Version
And through thy knowledge shall the weak brother perish, for whom Christ died?
Context
10 For if a man sees you who have knowledge sitting in an idol’s temple, won’t his conscience, if he is weak, be emboldened to eat things sacrificed to idols?
11 And through your knowledge, he who is weak perishes, the brother for whose sake Christ died.
12 Thus, sinning against the brothers, and wounding their conscience when it is weak, you sin against Christ.
