'Washing' in the Bible

Then Moses took Aaron and his sons; and after washing them with water,

Seven times he put oil on the altar and on all its vessels, and on the washing-basin and its base, to make them holy.

And the priest shall look on the sore after the washing, and behold, if the sore have not changed its appearance, and the sore have not spread, it is unclean: thou shalt burn it with fire: it is a fretting sore on what is threadbare or where the nap is gone.

And if the priest look, and, behold, the plague be somewhat dark after the washing of it; then he shall rend it out of the garment, or out of the skin, or out of the warp, or out of the woof:

And anyone on whom the unclean man puts his hands, without washing them in water, is to have his clothing washed and his body bathed in water and be unclean till evening.

And when a man who has a flow from his body is made clean from it, he is to take seven days to make himself clean, washing his clothing and bathing his body in flowing water, and then he will be clean.
