Passage
Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head.
Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head.
John 13:7 Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter.
John 13:8 Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.
John 13:9 Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head.
John 13:10 Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.
John 13:11 For he knew who should betray him; therefore said he, Ye are not all clean.
The verse centers on "simon", "peter", "saith", "lord", "feet", "only", "hands", and "head". It is saying that the verse draws attention to "simon" and "peter", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 8's "Peter saith unto him Thou shalt never..." into verse 10's "Jesus saith to him He that is...", so "simon" and "peter" belong inside that flow. In John context, the local focus is the identity of Jesus, new birth, eternal life, and belief and unbelief.
A plain takeaway is to answer the verse's own emphasis on "simon" and "peter" with trust shaped by these words, not by a vague optimism outside the passage.
