Passage
He riseth from supper, and laid aside his garments; and took a towel, and girded himself.
He riseth from supper, and laid aside his garments; and took a towel, and girded himself.
John 13:2 And supper being ended, the devil having now put into the heart of Judas Iscariot, Simon’s son, to betray him;
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?
The verse centers on "riseth", "supper", "laid", "aside", "garments", "took", "towel", and "girded". It is saying that the verse draws attention to "riseth" and "supper", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "Jesus knowing that the Father had given..." into verse 5's "After that he poureth water into a...", so "riseth" and "supper" 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 "riseth" and "supper" with trust shaped by these words, not by a vague optimism outside the passage.
