English: Rava said: Why are five negative commandments stated regarding blood?
Multiple lavin on blood — the Torah states several distinct prohibitions concerning blood, each teaching a separate aspect.
The Torah states several distinct prohibitions concerning blood, each teaching a separate aspect. Rava’s question opens an inquiry into why the prohibition is repeated in multiple formulations. The multiplicity is understood to generate distinct legal consequences rather than mere rhetorical emphasis, so that each lav addresses a different dimension of the ban on consuming blood.
