'Natural' in the Bible

Moreover, the fat of an animal that has died of natural causes and the fat of an animal torn by beasts may be used for any other purpose, but you must certainly never eat it.

"'Any person who eats an animal that has died of natural causes or an animal torn by beasts, whether a native citizen or a foreigner, must wash his clothes, bathe in water, and be unclean until evening; then he becomes clean.

He must not eat an animal that has died of natural causes or an animal torn by beasts and thus become unclean by it. I am the Lord.

If these men die a natural death, or if they share the fate of all men, then the Lord has not sent me.

And whoever touches the body of someone killed with a sword in the open fields, or the body of someone who died of natural causes, or a human bone, or a grave, will be unclean seven days.

The priests will not eat any bird or animal that has died a natural death or was torn to pieces by a wild animal.
