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

Ambrosiaster
AD 400
The person who is greater in rank or dignity cannot do without those who are lower. For there are things which a humbler person can do which an exalted one cannot, just as iron can do things which gold cannot. Because of this, the feet perform an honorable function for the head. Commentary on Paul’s Epistles.
