1 Corinthians 8:9-11

Young's Literal Translation

⁹ but see, lest this privilege of yours may become a stumbling-block to the infirm,

¹⁰ for if any one may see thee that hast knowledge in an idol's temple reclining at meat -- shall not his conscience -- he being infirm -- be emboldened to eat the things sacrificed to idols,

¹¹ and the brother who is infirm shall perish by thy knowledge, because of whom Christ died?
