English: “In all your dwellings” — why is this said? One might think: since they are written in the context of offerings, when there are offerings chelev and blood are forbidden, and when there are no offerings they are not forbidden.
Applicability outside the Temple era — the ban on chelev and blood applies in all places and times, not only when offerings are brought.
The ban on chelev and blood applies in all places and times, not only when offerings are brought. Because the prohibitions appear in the context of sacrificial law, one might have limited them to periods when the Temple service is active. The Torah’s “in all your dwellings” blocks that limitation and establishes the ban as a permanent, universal statute.
