Leviticus 11:36-39

³⁶'Only — a fountain or pit, a collection of water, is clean, but that which is coming against their carcase is unclean;

³⁷and when any of their carcase falleth on any sown seed which is sown — it is clean;

³⁸and when water is put on the seed, and any of its carcase hath fallen on it — unclean it is to you.

³⁹'And when any of the beasts which are to you for food dieth, he who is coming against its carcase is unclean till the evening;
