'Part' in the Bible

but our comely parts have not need. But God has tempered the body together, having given more abundant honour to the part that lacked;

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

but when that which is perfect has come, that which is in part shall be done away.

But I rejoice in the coming of Stephanas and Fortunatus and Achaicus; because they have supplied what was lacking on your part.
