Leviticus 11:35-38

³⁵Any part of the dead body of one of these, falling on anything, will make it unclean; if it is an oven or a cooking-pot it will have to be broken: they are unclean and will be unclean to you.

³⁶But at the same time a fountain or a place where water is stored for use will be clean; but anyone touching their dead bodies will be unclean.

³⁷If any part of the dead body of one of these gets on to any seed for planting, it is clean;

³⁸But if water is put on the seed, and any part of the dead body gets on to it, it will be unclean to you.
