1 Corinthians 12:20-25

But now there are many members, but one body. And the eye cannot say to the hand, “I have no need of you”; or again the head to the feet, “I have no need of you.” On the contrary, it is much truer that the members of the body which seem to be weaker are necessary; and those members of the body which we deem less honorable, on these we bestow more abundant honor, and our less presentable members become much more presentable, whereas our more presentable members have no need of it. But God has so composed the body, giving more abundant honor to that member which lacked, so that there may be no division in the body, but that the members may have the same care for one another.
