Vayikra 11:35-37

Orthodox Jewish Bible

³⁵ And everything whereupon any part of their nevelah falleth shall be tamei; whether it be oven, or stove, they shall be broken; for they are temei’im and shall be temei’im unto you.

³⁶ Nevertheless a spring or cistern, wherein there is a mikveh mayim (collection of water) shall be tahor; but that which toucheth their nevelah shall be tamei.

³⁷ And if any part of their nevelah fall upon any zera for sowing which is to be sown, it shall be tahor.
