'Part' in the Bible

For the body does not consist of only one part, but of many.

If the foot says, "Since I'm not a hand, I'm not part of the body," that does not make it any less a part of the body, does it?

And if the ear says, "Since I'm not an eye, I'm not part of the body," that does not make it any less a part of the body, does it?

Now if all of it were one part, there wouldn't be a body, would there?

If one part suffers, every part suffers with it. If one part is praised, every part rejoices with it.
