But [when] you are fasting, {put olive oil on your head} and wash your face
"Why do your disciples break the tradition of the elders? For they do not wash their hands when they eat {a meal}."
(For the Pharisees and all the Jews do not eat unless they wash their hands {ritually}, [thus] holding fast to the traditions of the elders.
And [when they come] from the marketplace, they do not eat unless they wash. And there are many other [traditions] which they have received [and] hold fast to--[for example,] the washing of cups and pitchers and bronze kettles and dining couches.)

He replied, "The man who is called Jesus made clay and smeared [it] on my eyes and said to me, 'Go to Siloam and wash!' So I went, and I washed, [and] I received sight."
Then he poured water into the washbasin and began to wash the feet of the disciples, and to wipe [them] dry with the towel {which he had tied around himself}.

Peter said to him, "You will never wash my feet {forever}!" Jesus replied to him, "Unless I wash you, you do not have a share with me."
Jesus said to him, "The one who has bathed {only needs} to wash [his] feet, but is completely clean. And you are clean, but not all [of you]."
