Passage
if then I did wash your feet--the Lord and the Teacher--ye also ought to wash one another's feet.
if then I did wash your feet--the Lord and the Teacher--ye also ought to wash one another's feet.
John 13:12 When, therefore, he washed their feet, and took his garments, having reclined (at meat) again, he said to them, `Do ye know what I have done to you?

John 13:14 if then I did wash your feet--the Lord and the Teacher--ye also ought to wash one another's feet.
John 13:15 `For an example I gave to you, that, according as I did to you, ye also may do;
John 13:16 verily, verily, I say to you, a servant is not greater than his lord, nor an apostle greater than he who sent him;
The verse centers on "wash", "feet--the", "lord", "teacher--ye", "ought", and "another's". It is saying that the verse draws attention to "wash" and "feet--the", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "ye call me The Teacher and The..." into verse 15's "For an example I gave to you...", so "wash" and "feet--the" 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 "wash" and "feet--the" with trust shaped by these words, not by a vague optimism outside the passage.
