Leviticus 11:37

And if [any part] of their carcass fall upon any sowing seed that is to be sown,.... That which is selected from the other seed in order to be sown, and which is laid by and laid up for that purpose; should the carcass, or any part of the carcass of a creeping thing fall upon an heap of it, into a vessel in which it was put, as a dead mouse or the like:

[yet] it shall be clean; be fit for use and sown in the earth; because being cast into the earth, and dying and quickening there, and then springing up again in stalk and ear, it would go through various changes before it became the food of man: the Targum of Jonathan describes it, such as is sown in its dryness, or being dry; for if it was wetted it was unfit for use, as follows.
