“ ‘If a person, either a citizen or a foreigner, eats an animal that died by itself or was killed by another animal, he must wash his clothes and bathe in water. He will be unclean until evening; then he will be clean.
This is a lasting rule. Those who sprinkle the cleansing water must also wash their clothes, and anyone who touches the water will be unclean until evening.
“Then someone who is clean will collect the ashes from the cow and put them in a clean place outside the camp. The Israelites will keep these ashes to use in the cleansing water, in a special ceremony to cleanse away sin.
