'Conscience' in the Bible

For my conscience is clear, but that does not vindicate me. It is the Lord who examines me.

But not everyone has this knowledge. Some people are so accustomed to idolatry that when they eat food that has been offered to an idol, their conscience becomes contaminated because it is weak.

For if anyone with a weak conscience sees you, who know better, eating in an idol's temple, he will be encouraged to eat what has been offered to idols, won't he?

Eat anything that is sold in the meat market without raising any question about it on the grounds of conscience,

If an unbeliever invites you to his house and you wish to go, eat whatever is set before you, raising no question on the grounds of conscience.

However, if someone says to you, "This was offered as a sacrifice," don't eat it, both out of consideration for the one who told you and also for the sake of conscience.

I mean, of course, his conscience, not yours. For why should my freedom be determined by someone else's conscience?
