'Wash' in the Bible
Yahweh said to Moses, "Go to the people, and sanctify them today and tomorrow, and let them wash their garments,
You shall bring Aaron and his sons to the door of the Tent of Meeting, and shall wash them with water.
You shall cut the ram into its pieces, and wash its innards, and its legs, and put them with its pieces, and with its head.
"You shall also make a basin of brass, and its base of brass, in which to wash. You shall put it between the Tent of Meeting and the altar, and you shall put water in it.
Aaron and his sons shall wash their hands and their feet in it.
When they go into the Tent of Meeting, they shall wash with water, that they not die; or when they come near to the altar to minister, to burn an offering made by fire to Yahweh.
So they shall wash their hands and their feet, that they not die: and it shall be a statute forever to them, even to him and to his descendants throughout their generations."
"You shall bring Aaron and his sons to the door of the Tent of Meeting, and shall wash them with water.
He set the basin between the Tent of Meeting and the altar, and put water therein, with which to wash.
