New King James Version (NKJV)
John 12
49 For I have not spoken on My own authority; but the Father who sent Me gave Me a command, what I should say and what I should speak.
50 And I know that His command is everlasting life. Therefore, whatever I speak, just as the Father has told Me, so I speak."
John 13
1 Now before the feast of the Passover, when Jesus knew that His hour had come that He should depart from this world to the Father, having loved His own who were in the world, He loved them to the end.
2 And supper being ended, the devil having already put it into the heart of Judas Iscariot, Simon’s son, to betray Him,
3 Jesus, knowing that the Father had given all things into His hands, and that He had come from God and was going to God,
4 rose from supper and laid aside His garments, took a towel and girded Himself.
5 After that, He poured water into a basin and began to wash the disciples’ feet, and to wipe them with the towel with which He was girded.
6 Then He came to Simon Peter. And Peter said to Him, "Lord, are You washing my feet?"
7 Jesus answered and said to him, "What I am doing you do not understand now, but you will know after this."
8 Peter said to Him, "You shall never wash my feet!" Jesus answered him, "If I do not wash you, you have no part with Me."
9 Simon Peter said to Him, "Lord, not my feet only, but also my hands and my head!"
