John Gill, on Neh 12:39

“And the two choirs of them that gave praise stood still at the house of God, and I and the half of the magistrates with me.”

“And Maaseiah, and Shemaiah, and Eleazar, and Uzzi, and Jehohanan, and Malchijah, and Elam, and Ezer,.... These seem to be all priests that blew the trumpets: and the singers sang loud, with Jezrahiah their overseer; these were the Levites, that sung the songs of praise vocally, and raised their voices very high, Jezrahiah being precentor, who led the tune, as well as played on instruments.”
