Leviticus 11:30

And he that beareth the carcase of them shall wash his clothes, and be unclean until the even: they [are] unclean unto you.

These also [shall be] unclean unto you among the creeping things that creep upon the earth; the weasel, and the mouse, and the tortoise after his kind,

These [are] unclean to you among all that creep: whosoever doth touch them, when they be dead, shall be unclean until the even.

And upon whatsoever [any] of them, when they are dead, doth fall, it shall be unclean; whether [it be] any vessel of wood, or raiment, or skin, or sack, whatsoever vessel [it be], wherein [any] work is done, it must be put into water, and it shall be unclean until the even; so it shall be cleansed.
