Why Scripture Bars the Old, the Sick, and the Foul Animal

"From the flock, from the sheep, or from the goats" (Leviticus 1:10) excludes the aged, the sick, and the foul-smelling animal. And all three exclusions are necessary. For if the Merciful One had written only one, I would have said that He meant to exclude the aged, which does not recover and become sound again, but the sick, which does recover and become sound, you might say is not excluded. Or, on the other hand, He meant to exclude the sick, since that is not its natural state, but the aged, since that is its natural state, you might say is not excluded. And if the Merciful One had written two, I would have said He meant to exclude those that are emaciated, but the foul-smelling animal, which is not emaciated, you might say is not excluded; or, on the other hand, He meant to exclude the foul-smelling because it is loathsome, but those animals that are not loathsome you might say are not excluded. Therefore all three are necessary.
