Leviticus 11:32–33
32 And anything on which any of them falls when they are dead shall be unclean, whether it is an article of wood or a garment or a skin or a sack, any article that is used for any purpose. mIt must be put into water, and it shall be unclean until the evening; then it shall be clean. 33 And if any of them falls into any earthenware vessel, all that is in it shall be unclean, and you nshall break it.
