Passage
After that he poureth water into a bason, and began to wash the disciples’ feet, and to wipe them with the towel wherewith he was girded.
After that he poureth water into a bason, and began to wash the disciples’ feet, and to wipe them with the towel wherewith he was girded.
John 13:3 Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God;
John 13:4 He riseth from supper, and laid aside his garments; and took a towel, and girded himself.
John 13:5 After that he poureth water into a bason, and began to wash the disciples’ feet, and to wipe them with the towel wherewith he was girded.
John 13:6 Then cometh he to Simon Peter: and Peter saith unto him, Lord, dost thou wash my feet?
John 13:7 Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter.
The verse centers on "after", "poureth", "water", "bason", "began", "wash", "disciples", and "feet". It is saying that the verse draws attention to "after" and "poureth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "He riseth from supper and laid aside..." into verse 6's "Then cometh he to Simon Peter and...", so "after" and "poureth" 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 "after" and "poureth" with trust shaped by these words, not by a vague optimism outside the passage.
