1 Corinthians 8:11-13

Young's Literal Translation

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

¹² and thus sinning in regard to the brethren, and smiting their weak conscience -- in regard to Christ ye sin;

¹³ wherefore, if victuals cause my brother to stumble, I may eat no flesh -- to the age -- that my brother I may not cause to stumble.
