Vayikra 11:34-36

Orthodox Jewish Bible

³⁴ Of all okhel which may be eaten, that on which such mayim cometh shall be tamei; and all mashkeh that may be drunk in every such vessel shall be tamei.

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.
