Nehemiah 12:42 Meaning and Commentary

Nehemiah 12:42

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.

Nehemiah 12:42 In-Context

40 And the two thanksgiving companies stand in the house of God, and I and half of the prefects with me,
41 and the priests, Eliakim, Maaseiah, Miniamin, Michaiah, Elioenai, Zechariah, Hananiah, with trumpets,
42 and Masseiah, and Shemaiah, and Eleazar, and Uzzi, and Jehohanan, and Malchijah, and Elam, and Ezer, and the singers sound, and Jezrahiah the inspector;
43 and they sacrifice on that day great sacrifices and rejoice, for God hath made them rejoice [with] great joy, and also, the women and the children have rejoiced, and the joy of Jerusalem is heard -- unto a distance.
44 And certain are appointed on that day over the chambers for treasures, for heave-offerings, for first-fruits, and for tithes, to gather into them out of the fields of the cities the portions of the law for priests, and for Levites, for the joy of Judah [is] over the priests, and over the Levites, who are standing up.
