Leviticus 11:31-32 ▼

31 These [creatures] are unclean to you among all that swarm; whoever touches them when they are dead becomes unclean until evening.

32 Also anything on which one of them falls after dying becomes unclean, whether it is an article of wood or clothing, or a skin, or a sack—any article that is used—it must be put in water, and will be unclean until the evening; then it becomes clean.
