1 Corinthians 8
10 Ref For if a man see thee who hast knowledge sitting at meat in an idol's temple, will not his conscience, if he is weak, be emboldened to eat things sacrificed to idols?
11 Ref For through thy knowledge he that is weak perisheth, the brother for whose sake Christ died.
12 Ref And thus, sinning against the brethren, and wounding their conscience when it is weak, ye sin against Christ.
