Numbers 31:20; Leviticus 11:32

20 You shall purify every garment, every article of skin, all work of goats' hair, and every article of wood.


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.
