What does the Bible say about one part of the body saying it has no need of another?

Les teaches from the bodily members analogy that just as the foot cannot say it is not of the body because it is not a hand, and the ear cannot say it is not of the body because it is not an eye, so the eye cannot say to the hand, 'I have no need of thee,' nor the head to the feet, 'I have no need of you.' The whole body functions together, and even the smallest member matters, as an amputee misses a little toe almost as much as a complete hand.
