Leviticus 17:15 And every soul that eateth that which died of itself, or that which was torn with beasts, whether it be one of your own country, or a stranger, he shall both wash his clothes, and bathe himself in water, and be unclean until the even: then shall he be clean.
He ate it and he might get sick. Stay away from him till you see what happens. The animal died and we aren’t sure why it died. It might be sick. It might have something that could affect you. So if someone eats that animal you should consider them contaminated till you know that they are ok.
Another verse showing you how the Bible is the Word of God. They knew things that they shouldn’t have known. They had not been discovered yet, scientifically. God gave them wisdom.
You have the Word of God in your hands.
