Exodus 30:21

They shall wash their hands and feet with water, whenever they shall go into the tabernacle of witness; they shall wash themselves with water, that they die not; and it shall be for them a perpetual statute, for him and his posterity after him.

So they shall wash their hands and their feet, that they die not: and it shall be a statute for ever to them, even to him and to his seed throughout their generations.

So they shall wash their hands and their feet, that they not die. This shall be a statute forever to them, even to him and to his descendants throughout their generations.”
