'Wash' in the Bible
"Go and wash in the pool of Siloam" --the name means 'Sent.' So he went and washed his eyes, and returned able to see.
"He whose name is Jesus," he answered, "made clay and smeared my eyes with it, and then told me to go to Siloam and wash. So I went and washed and obtained sight."
Then He poured water into a basin, and proceeded to wash the feet of the disciples and to wipe them with the towel which He had put round Him.
When He came to Simon Peter, Peter objected. "Master," he said, "are *you* going to wash my feet?"
"Never, while the world lasts," said Peter, "shall you wash my feet." "If I do not wash you," replied Jesus, "you have no share with me."
"Master," said Peter, "wash not only my feet, but also my hands and my head."
"Any one who has lately bathed," said Jesus, "does not need to wash more than his feet, but is clean all over. And you my disciples are clean, and yet this is not true of all of you."
If I then, your Master and Rabbi, have washed your feet, it is also your duty to wash one another's feet.
