'Part' in the Bible

If the foot would say, "Because I'm not the hand, I'm not part of the body," it is not therefore not part of the body.

If the ear would say, "Because I'm not the eye, I'm not part of the body," it's not therefore not part of the body.

whereas our presentable parts have no such need. But God composed the body together, giving more abundant honor to the inferior part,

For we know in part, and we prophesy in part;

For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I will know fully, even as I was also fully known.

I rejoice at the coming of Stephanas, Fortunatus, and Achaicus; for that which was lacking on your part, they supplied.
