10 Whoever touches anything that was under him will be unclean until evening, and whoever carries such things is to wash his clothes and bathe with water, and he will remain unclean until evening.
11 If the man with the discharge touches anyone without first rinsing his hands in water,(A) the person who was touched is to wash his clothes and bathe with water, and he will remain unclean until evening.
12 Any clay pot that the man with the discharge touches must be broken, while any wooden utensil must be rinsed with water.(B)
