Albert Barnes Commentary Nehemiah 12:44

"And on that day were men appointed over the chambers for the treasures, for the heave-offerings, for the first-fruits, and for the tithes, to gather into them, according to the fields of the cities, the portions appointed by the law for the priests and Levites: for Judah rejoiced for the priests and for the Levites that waited." — Nehemiah 12:44 (ASV)

Judah rejoiced - Judah’s satisfaction with the priests and Levites took the shape of increased offerings, more ample tithes, and the like, from which the appointment of treasuries and treasurers became necessary.
