9 “‘Everything the man sits on when riding will be unclean,

10 and whoever touches any of the things that were under him will be unclean till evening; whoever picks up those things must wash his clothes and bathe with water, and he will be unclean till evening.

11 “‘Anyone the man with a discharge touches without rinsing his hands with water must wash his clothes and bathe with water, and he will be unclean till evening.
