'Duties' in the Bible

I appointed over the storerooms: Shelemiah the priest, Zadok the scribe, and Pedaiah from the descendants of Levi; and next to them Zaccur's son Hanan, the grandson of Mattaniah, because they had been considered faithful. Their duties were to distribute to their associates.

So I purified them from everything foreign and assigned specific duties to each of the priests and Levites.
