Leviticus 11:31-33

Young's Literal Translation

³¹ these [are] the unclean to you among all which are teeming; any one who is coming against them in their death is unclean till the evening.

³² `And anything on which any one of them falleth, in their death, is unclean, of any vessel of wood or garment or skin or sack, any vessel in which work is done is brought into water, and hath been unclean till the evening, then it hath been clean;

³³ and any earthen vessel, into the midst of which [any] one of them falleth, all that [is] in its midst is unclean, and it ye do break.
