'Conscience' in the Bible

But this knowledge is not shared by all. And some, by being accustomed to idols in former times, eat this food as an idol sacrifice, and their conscience, because it is weak, is defiled.

For if someone weak sees you who possess knowledge dining in an idol's temple, will not his conscience be "strengthened" to eat food offered to idols?

If you sin against your brothers or sisters in this way and wound their weak conscience, you sin against Christ.

Eat anything that is sold in the marketplace without questions of conscience,

If an unbeliever invites you to dinner and you want to go, eat whatever is served without asking questions of conscience.

But if someone says to you, "This is from a sacrifice," do not eat, because of the one who told you and because of conscience --

I do not mean yours but the other person's. For why is my freedom being judged by another's conscience?
