John Gill, on Neh 12:43

“They appointed also in that day men over the storehouses of the treasure, for the libations, and for the firstfruits, and for the tithes, that the rulers of the city might bring them in by them in honour of thanksgiving, for the priests and Levites: for Juda was joyful in the priests and Levites that assisted.”

“For in the days of David and Asaph of old there were chief of the singers,.... Persons appointed over the rest to instruct them, and see that they did their work aright, as besides Asaph, Haman, and Jeduthun, and their sons, Ch1 25:2 and songs of praise and thanksgiving unto God; such were made by them, some under divine inspiration, which bear the names of David and Asaph, as may be observed in the book of Psalms.”
