Simon Peter saith unto him,.... Being convinced of his mistake in not submitting to Christ, fearing he should he deprived of communion with him, than which nothing was more desirable to him, or more highly esteemed of by him, says,Lord, not my feet only, but also my hands and my head; which shows the sense he had of the general pollution of his nature, and the need he stood in particularly of having his feet, hands, and head washed both as a minister, and a believer.
By his "feet" may be meant, either the grace of faith, which is the foot of the soul, by which it goes to Christ, and walks on in him, and was not without its imperfections; or the affections of the mind, which are that to the soul, as feet are to the body; and when they move right, move heavenward, Godward, and Christward; but sometimes they are inordinate, and cleave to the things of this world: or the outward life and conversation is meant, which is attended with daily infirmities; and each of these need washing in the blood of Christ.
His "hands" may design all his actions, works, services, duties, and performances, the hand being the instrument of action; and not only the hands of wicked men, but even of saints, need washing, their best righteousnesses being as filthy rags.
