Orthodox Jewish Bible

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.

³⁸ But if any mayim be put upon the zera, and any part of their nevelah fall thereon, it shall be tamei unto you.
