Albert Barnes on John 13:6

Dost thou wash my feet? Every word here is emphatic. Dost thou-- the Son of God, the Messiah--perform the humble office of a servant--toward me, a sinner? This was an expression of Peter's humility, of his reverence for Jesus, and also a refusal to allow him to do it. It is possible, though not certain from the text, that he came to Simon Peter first.

(1) "Peter", or "he" (g) "dost thou wash my feet" Mt 3:14
