Leviticus 11:31-33

American Standard Version

³¹ These are they which are unclean to you among all that creep: whosoever doth touch them, when they are dead, shall be unclean until the even. ³² And upon whatsoever any of them, when they are dead, doth fall, it shall be unclean; whether it be any vessel of wood, or raiment, or skin, or sack, whatsoever vessel it be, wherewith any work is done, it must be put into water, and it shall be unclean until the even; then shall it be clean. ³³ And every earthen vessel, whereinto any of them falleth, whatsoever is in it shall be unclean, and it ye shall break.
