He that eateth Unwittingly, for if he did it knowingly, it was a presumptuous sin against an express law, (Deuteronomy 14:21,) and therefore punished as such. Every creeping thing Except those expressly excepted, Leviticus 11:29. Upon the belly As worms and snakes. Upon all four As toads and divers serpents.
