Killing an animal and eating its blood is a crime.
Any Israelite or any foreigner residing among you who hunts any animal or bird that may be eaten must drain out the blood and cover it with earth, because the life of every creature is its blood. That is why I have said to the Israelites, “You must not eat the blood of any creature, because the life of every creature is its blood; anyone who eats it must be cut off.” - Lev.17:13,14
Finding a dead animal and eating its unbled flesh is not a crime.
Anyone, whether native-born or foreigner, who eats anything found dead or torn by wild animals must wash their clothes and bathe with water, and they will be ceremonially unclean till evening; then they will be clean. - Lev.17:15
Please explain the difference Fishy and reconcile it with Deut 14. Don't just keep repeating the same phrase out of context.
