Exodus 30:21

They shall wash their hands and their feet , so that they may not die . It shall be a statute forever to them, even to him and to his offspring throughout their generations .

they shall wash their hands and feet so that they will not die. This is to be a lasting ordinance for Aaron and his descendants for the generations to come.”

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.
