English: “From the blood of the bull” — from the life-blood, and not from the skin-blood and not from the residual blood.
Miyut of non-life blood — only the dam ha-nefesh (life-blood at slaughter) is valid for the service; skin-blood and residual blood are excluded.
Only the dam ha-nefesh (life-blood at slaughter) is valid for the service; skin-blood and residual blood are excluded. The verse’s language is taken to specify the primary blood that issues at the moment of shechitah. Blood that seeps from the skin or remains as residual after the main flow is not the blood required for the chatas service of the High Priest’s bull.
