What does Leviticus 17:15 mean?

If someone eats an animal that died naturally or was killed by another animal, they have to wash their clothes and bathe. They'll be unclean until evening, then they're clean again. Leviticus 17:15 - Modern Text Bible

(Eating animals that weren't properly killed made a person ritually unclean, but the impurity was temporary and could be fixed by washing.)
