'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.

As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one.

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.

What say I then? that the idol is any thing, or that which is offered in sacrifice to idols is any thing?

But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils.

But if any man say unto you, This is offered in sacrifice unto idols, eat not for his sake that shewed it, and for conscience sake: for the earth is the Lord's, and the fulness thereof:

Even if I give away everything that I have and sacrifice myself, but have no love, I gain nothing.
