'Wash' in the Bible

But when you fast, put oil on your head [as you normally would to groom your hair] and wash your face

(For the Pharisees and all of the Jews do not eat unless they carefully wash their hands, holding firmly to the traditions of the elders;

The Pharisee noticed this and was surprised that Jesus did not first ceremonially wash before the meal.

And He said to him, “Go, wash in the pool of Siloam” (which is translated, Sent). So he went away and washed, and came back seeing.

He replied, “The Man called Jesus made mud and smeared it on my eyes and told me, ‘Go to Siloam and wash.’ So I went and washed, and I received my sight!”

Then He poured water into the basin and began washing the disciples’ feet and wiping them with the towel which was tied around His waist.

When He came to Simon Peter, he said to Him, “Lord, are You going to wash my feet?”

Peter said to Him, “You will never wash my feet!” Jesus answered, “Unless I wash you, you have no part with Me [we can have nothing to do with each other].”

Simon Peter said to Him, “Lord, [in that case, wash] not only my feet, but also my hands and my head!”

Jesus said to him, “Anyone who has bathed needs only to wash his feet, and is completely clean. And you [My disciples] are clean, but not all of you.”

So if I, the Lord and the Teacher, washed your feet, you ought to wash one another’s feet as well.

Now, why do you delay? Get up and be baptized, and wash away your sins by calling on His name [for salvation].’
