When one of them dies and falls on something, that article becomes unclean; any article of wood, clothing, leather, sackcloth, or any implement used for work must be rinsed with water and will remain unclean until evening; then it will be clean.
Jewish Publication Society of America Version (JPS1917) - Leviticus 11:32 >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.
