"He may eat it" an unbled animal found dead.
Cofty argues that "If God allowed an animal found dead and un-bled to be eaten by anyone whatsoever, it could contradict God's command to Noah which is binding upon all humans, Jews and non-Jews "flesh with its life, its blood you must not eat" -yet in Deut 14:21 God seems to give permission ( "he may eat") to the Gentile. Cofty points out a distinction between the blood of a slaughtered animal for food and the blood of an animal found dead, as the reason why God allowed animals found dead to be eaten by Gentiles apparently without having to bled.
So, on the one hand wt teaches that blood is sacred to God and cannot be eaten but on the other hand Cofty is saying that the scriptures suggest that since God allowed unbled animals to be eaten, ( and God does seem to say that in Deut 14:21)- and thereby the dead animal eater is also eating the flesh with the blood in contrast with Gen 9:4- It is ok to eat blood just as long as "no life was taken" as cofty argues in his OP. Cofty, also argues that if a worshipper of Jehovah in ancient Israel ate an unbled animal found dead, he would not become guilty of a sin incurring the death penalty, because if that was the case, the scriptures would plainly say so, but all the scriptures say is that it was an unclean act, prohibited by law, yes, but still only an unclean act and not a sin incurring the death penalty because nowhere in the Torah does it state directly that the penalty for eating an animal found dead (unbled) resulted in the death penalty but only resulted in the state of uncleanness requiring restoration as provided in the related scripture.
Cofty's argument is that God allowed blood to be eaten and in fact blood was eaten indirectly when God allowed animals found dead to be eaten with no punishment for eating an unbled carcass in seeming violation of Gen 9:4. Thus such blood from dead animals was not being viewed by God as sacred but meaningless to God. Cofty concludes that the only blood sacred to God is the one that comes from an animal that is slaughtered for food.
But can the blood of a dead animal or a live animal or that of a living or dead human being be consumed without violating God's law? ( Adultery, killing , stealing, etc. violate God's laws) Or is eating blood from a creature that has not been killed for food ok or at the most an unclean act?
