'Sacrifice' in the Bible

Get rid of the old yeast so that you may be dough of a new kind; for in fact you *are* free from corruption. For our Passover Lamb has already been offered in sacrifice--even Christ.

No, but that which the Gentiles sacrifice, they sacrifice to demons, not to God; and I would not have you have fellowship with one another through the demons.

But if any one tells you, "This food has been offered in sacrifice;" abstain from eating it--out of respect for him who warned you, and, as before, for conscience' sake.
