'Conscience' in the Bible

However not all men have this knowledge; but some, being accustomed to the idol until now, eat food as if it were sacrificed to an idol; and their conscience being weak is defiled.

For if someone sees you, who have knowledge, dining in an idol’s temple, will not his conscience, if he is weak, be strengthened to eat things sacrificed to idols?

And so, by sinning against the brethren and wounding their conscience when it is weak, you sin against Christ.

Eat anything that is sold in the meat market without asking questions for conscience’ sake;

If one of the unbelievers invites you and you want to go, eat anything that is set before you without asking questions for conscience’ sake.

But if anyone says to you, “This is meat sacrificed to idols,” do not eat it, for the sake of the one who informed you, and for conscience’ sake;

I mean not your own conscience, but the other man’s; for why is my freedom judged by another’s conscience?
