English: “And every animal” — to include the afterbirth; one might have thought even if part of it emerged, therefore the verse says “it you may eat” — it, and not its afterbirth.
On the daf / in context: If part of the placenta emerged before the mother’s slaughter, the remaining portion and any fetus still inside become forbidden.
Type of Learning
