'Falls' in the Bible

and anything into which their carcass falls becomes unclean. An oven or stove is to be broken in pieces. They're unclean and therefore unclean for you.

If their carcass falls on a seed, which is for sowing, what is to be sown is clean.

But if water is put on the seed and part of their carcass falls on it, then it has become unclean for you.
