KJB,
I understand. Sometimes people (including me) do not really read the Scripture passages when posted.
I will site the passages with as much context as in to at least have it make sense.
They are the same ones as given by Cephas above, taken from
www.scriptureCatholic.com , except that the guy who runs the website sometimes seems to stretch the verses too much, and even other Catholic apologists (professional and amateru alike) critique him for that.
In here I lay them out and put out those who I did not think truly fit in. The parenthesis are my comments.

Exodus 30:17
The LORD said to Moses,
"You shall also make a laver of bronze, with its base of bronze, for washing. And you shall put it between the tent of meeting and the altar, and you shall put water in it, with which Aaron and his sons shall wash their hands and their feet.
When they go into the tent of meeting, or when they come near the altar to minister, to burn an offering by fire to the LORD, they shall wash with water, lest they die. They shall wash their hands and their feet, lest they die: it shall be a statute for ever to them, even to him and to his descendants throughout their generations."

Numbers 5:17

Numbers 8:5-7
And the LORD said to Moses,
"Take the Levites from among the people of Israel, and cleanse them.
And thus you shall do to them, to cleanse them: sprinkle the water of expiation upon them, and let them go with a razor over all their body, and wash their clothes and cleanse themselves."

1 Kings 7:38-39 (the baths, possibly suggesting water in worship)
And he made ten lavers of bronze; each laver held forty baths, each laver measured four cubits, and there was a laver for each of the ten stands.
And he set the stands, five on the south side of the house, and five on the north side of the house; and he set the sea on the southeast corner of the house.

John 9:6-7
As he said this, he spat on the ground and made clay of the spittle and anointed the man's eyes with the clay, saying to him, "Go, wash in the pool of Silo'am" (which means Sent). So he went and washed and came back seeing.

John 13:4-10 (perhaps alluding to OT use of water)
[Jesus] rose from supper, laid aside his garments, and girded himself with a towel.
Then he poured water into a basin, and began to wash the disciples' feet, and to wipe them with the towel with which he was girded.
He came to Simon Peter; and Peter said to him, "Lord, do you wash my feet?"
Jesus answered him, "What I am doing you do not know now, but afterward you will understand."
Peter said to him, "You shall never wash my feet." Jesus answered him, "If I do not wash you, you have no part in me."
Simon Peter said to him, "Lord, not my feet only but also my hands and my head!"
Jesus said to him, "He who has bathed does not need to wash, except for his feet, but he is clean all over; and you are clean, but not every one of you."

John 19:34
