Vander....The Deuteronomists were repeating/revising the Levitical code. Thats why it's called Deuteronomy "2nd law'. They made many alterations. The point Coffy was making is the Leviticus passage makes no distinction between merely touching and eating a carcass, the ritual uncleanness was due the contact with death. The Deuteronomists prohibited Jews alone from eating it, without mentioning a ritual remedy. Perhaps ironically the Leviticus code does not differentiate the foreigner from the Jew in regards eating found dead animals but the Deuteronomists did by allowing the sale of found dead animals for food to nonIsraelites living among them.
Leviticus 11:40
Whoever eats from the carcass must wash his clothes and will be unclean until evening, and anyone who picks up the carcass must wash his clothes and will be unclean until evening.
Leviticus 17:15
And any person, whether native or foreigner, who eats anything found dead or mauled by wild beasts must wash his clothes and bathe with water, and he will be unclean until evening; then he will be clean.
**Contrast the Deuteronomist who was much more concerned about Jews only:
Deuteronomy 14:21
You are not to eat any carcass; you may give it to the foreigner residing within your gates, and he may eat it, or you may sell it to a foreigner. For you are a holy people belonging to the LORD your God.
Leviticus 7:24
The fat of an animal found dead or mauled by wild beasts may be used for any other purpose, but you must not eat it.
(No mention of avoiding the carcass because of uncleaness)
