Leviticus 11:34

31 These are they which are unclean to you among all that creep: whoever does touch them, when they are dead, shall be unclean until the even.

32 On whatever any of them, when they are dead, does fall, it shall be unclean; whether it be any vessel of wood, or clothing, or skin, or sack, whatever vessel it be, with which any work is done, it must be put into water, and it shall be unclean until the even; then shall it be clean.

33 Every earthen vessel, into which any of them falls, whatever is in it shall be unclean, and it you shall break.

34 All food [therein] which may be eaten, that on which water comes, shall be unclean; and all drink that may be drunk in every [such] vessel shall be unclean.

35 Every thing whereupon [any part] of their carcass falls shall be unclean; whether oven, or range for pots, it shall be broken in pieces: they are unclean, and shall be unclean to you.

36 Nevertheless a spring or a pit in which is a gathering of water shall be clean: but that which touches their carcass shall be unclean.

37 If [anything] of their carcass fall on any sowing seed which is to be sown, it is clean.
