1 Corinthians 12:22-25

No, those parts which seem to be feeble are the more necessary; And to those parts of the body which seem to have less honour we give all the more honour; and to those parts of the body which are a cause of shame to us we give the greater respect; But those parts of the body which are beautiful have no need of such care: and so the body has been joined together by God in such a way as to give more honour to those parts which had need of it; So that there might be no division in the body; but all the parts might have the same care for one another.
