Kommentar zu Esra 1:10

bowls Heb. כְּפוֹרֵי, bowls, and they were called כְּפוֹרֵי from an expression of wiping, like (Bava Mezia 24b): “who wiped (דְּכָפַר) his hands on his neighbor’s cloak,” because the one who would receive the blood in a bowl would wipe the squirtings of the blood that splattered on his hand on the rim of the bowl.

secondary Heb. מִשְּׁנִים, secondary ones, other vessels of another kind.
