'Scruples' in the Bible

For if someone sees you, a person having knowledge, eating in an idol’s temple, then if he is weak, will he not be encouraged to eat things sacrificed to idols [and violate his own convictions]?

[Regarding meat offered to idols:] Eat anything that is sold in the meat market without asking any questions for the sake of your conscience,

If one of the unbelievers invites you [to a meal at his home] and you want to go, eat whatever is served to you without asking questions [about its source] for the sake of your conscience.

and by conscience I mean for the sake of the other man’s, not yours. For why is my freedom [of choice] judged by another’s conscience [another’s ethics—another’s sense of right and wrong]?
