36 Simon Peter then says to Him, "Lord (Master), to what place are you proceeding to lead under (or: where are you going)?" Jesus decidedly answered, "To what place I proceed leading under (or; departing) you continue unable (still have no power) to follow Me now, but you will follow afterwards (will subsequently follow).
37 Peter now says to Him, "Lord (Master), why (through what situation or circumstance) am I not presently able to keep on following you right now? I will continue placing my soul over You (or: I will proceed to be laying [down] my soul-life, inner being, and self for Your sake)."
