Nehemiah 11:22

i.e. Were to take care at Jerusalem for the supply of such things as were necessary for the temple and the service of God, from time to time, whilst others minded the outward business, Nehemiah 11:16. And this office was very proper for them, both as they were Levites, to whose care those things belonged; and as they were singers, who were not to come to Jerusalem by turns, as other Levites, and as the priests did, but were constantly to reside there, and therefore were more capable of minding this business. Besides, their employment was not so frequent nor so great as some others were, and therefore they had more leisure for it.
