'Conscience' in the Bible

But knowledge is not in all: but some, with conscience of the idol, until now eat as of a thing sacrificed to idols; and their conscience, being weak, is defiled.

For if any one see thee, who hast knowledge, sitting at table in an idol-house, shall not his conscience, he being weak, be emboldened to eat the things sacrificed to the idol?

Now, thus sinning against the brethren, and wounding their weak conscience, ye sin against Christ.

Everything sold in the shambles eat, making no inquiry for conscience sake.

But if any one of the unbelievers invite you, and ye are minded to go, all that is set before you eat, making no inquiry for conscience sake.

But if any one say to you, This is offered to holy purposes, do not eat, for his sake that pointed it out, and conscience sake;

but conscience, I mean, not thine own, but that of the other: for why is my liberty judged by another conscience?
