Thanks C o f t y. Nice research. Two questions though. How do we know for sure that if an Israelite found a dead animal he didn't have to bleed it. I know the text doesn't say he must bleed it , but could that just be because the preceding verses already stated one must bleed an animal first and therefore bleeding is implied? Also, why is it impossible to bleed an animal already dead? Thanks. - Chris Tann
Sorry I missed this question 6 months ago.
The answer to both your questions is the same.
It is physically impossible to bleed a dead animal. The blood congeals within minutes.
If an Israelite found one of his animals dead and cold he had a dilemma. If he buried it he became unclean for touching a dead body. If he ate it the result was the same.
He didn't take the life and therefore the blood has no symbolic significance.
39 “‘If an animal that you are allowed to eat dies, anyone who touches its carcass will be unclean till evening. 40 Anyone who eats some of its carcass must wash their clothes, and they will be unclean till evening. Anyone who picks up the carcass must wash their clothes, and they will be unclean till evening. - lev 11
