וַיִּשְׁחַ֖ט אֶת־הָעֹלָ֑ה וַ֠יַּמְצִאוּ בְּנֵ֨י אַהֲרֹ֤ן אֵלָיו֙ אֶת־הַדָּ֔ם וַיִּזְרְקֵ֥הוּ עַל־הַמִּזְבֵּ֖חַ סָבִֽיב׃
Il immola l’holocauste; les fils d’Aaron lui passèrent le sang, et il en arrosa le tour de l’autel.
Ibn Ezra
One kohen will slaughter [singular] the animal, but many will throw [plural] the blood , as it is written: “Aaron’s sons handed him the blood” [9:12].
