<p>13:38 <i>Jesus answered: Will you lay down your life for me? Truly, truly, I say to you: The cock shall not crow, till you have denied me three times</i>- As noted on:37, Peter had rather missed the point anyway. The Lord was 'going' not to simply die <i>per se</i>, but into the profoundest spiritual glorification process with the Father which Peter was too immature to enter. But the Lord goes along with Peter's literalism, and gently points out to him that he was not even up to dying with Him, let alone entering the spiritual things which were implied in the Lord's death and where He was 'going'. The issues relating to the Lord's words to Peter here are discussed on Mt. 26:34,35.</p>
