John Gill Commentary Nehemiah 8:7

"Also Jeshua, and Bani, and Sherebiah, Jamin, Akkub, Shabbethai, Hodiah, Maaseiah, Kelita, Azariah, Jozabad, Hanan, Pelaiah, and the Levites, caused the people to understand the law: and the people [stood] in their place." — Nehemiah 8:7 (ASV)

Also Jeshua, and Bani, and Sherebiah, Jamin, Akkub,
Shabbethai, Hodijah, Maaseiah, Kelita, Azariah, Jozabad, Hanan,
Pelaiah, and the Levites
That is, others of them besides those named; for they seem all to be Levites, unless they can be thought to be priests, and so the Levites are distinguished from them; but the former seems evident from (Nehemiah 9:4–6) these also

caused the people to understand the law ;
as well as Ezra; from which it is plain that he did not only read the law, but gave the sense of it, especially where there was any seeming difficulty, and these men were assisting in the same work: and the people stood in their place; to hear the law read and explained; they did not move from their first station, but continued in it from morning to noon; they were both attentive and constant.
