1 Corinthians 12:19-23

And if they were all one member, where were the body?

But now are they many members, yet but one body.

And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.

Nay, much more those members of the body, which seem to be more feeble, are necessary:

And those members of the body, which we think to be less honourable, upon these we bestow more abundant honour; and our uncomely parts have more abundant comeliness.
