“Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.”
King James Version (KJV)
13:8 If I wash thee not - If thou dost not submit to my will, thou hast no part with me - Thou art not my disciple. In a more general sense it may mean, If I do not wash thee in my blood, and purify thee by my Spirit, thou canst have no communion with me, nor any share in the blessings of my kingdom.
Joh 13:8 If I wash thee not, thou hast no part with me. Washing, with the Jews, was a symbolical act, signifying purification from uncleanliness. That Christ referred to more than a washing with water was understood by Peter as is evident from his reply. Christ could only wash with blood the obedient.
