1 Corinthians 8:10-12

Godbey(i) 10 For if any one may see you having knowledge sitting at the table in the idol temple, will not the conscience of him, being weak, be encouraged to eat things sacrificed to the idols? 11 For the weak one is destroyed by your knowledge, the brother for whom Christ died. 12 And you, sinning so against the brethren, and wounding their weak conscience, are sinning against Christ.
