'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 if the priest sees that the mark is less bright after the washing, then let him have it cut out of the clothing or the leather or from the threads of the material:

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.
