'Conscience' in the Bible

Howbeit there is not in all men that knowledge: but some, being used until now to the idol, eat as of a thing sacrificed to an idol; and their conscience being weak is defiled.

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?

And thus, sinning against the brethren, and wounding their conscience when it is weak, ye sin against Christ.

Whatsoever is sold in the shambles, eat, asking no question for conscience'sake,

If one of them that believe not biddeth you to a feast , and ye are disposed to go; whatsoever is set before you, eat, asking no question for conscience'sake.

But if any man say unto you, This hath been offered in sacrifice, eat not, for his sake that showed it, and for conscience sake:

conscience, I say, not thine own, but the other's; for why is my liberty judged by another conscience?
