Leviticus 11:36

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.

38 But if water be put on the seed, and [anything] of their carcass fall thereon, it is unclean to you.

39 If any animal, of which you may eat, die; he who touches the carcass of it shall be unclean until the even.
