וּמֵהֶ֖ם עַל־כְּלֵ֣י הָעֲבוֹדָ֑ה כִּֽי־בְמִסְפָּ֣ר יְבִיא֔וּם וּבְמִסְפָּ֖ר יוֹצִיאֽוּם׃
Alguns deles estavam encarregados dos utensílios do serviço, pois estes por conta eram trazidos e por conta eram tirados.
Rashi
And some of them were in charge of the service vessels כְּלֵי הָעֲבוֹדָה, the service vessels - they would take them out by number and bring them by number.
