Leviticus 11:37-39

New American Standard Bible

³⁷ Now if a part of their carcass falls on any seed for sowing which is to be sown, it is clean. ³⁸ But if water is put on the seed and a part of their carcass falls on it, it is unclean to you.

³⁹ ‘Also if one of the animals dies which you have for food, the one who touches its carcass becomes unclean until evening.
