John Gill Commentary Nehemiah 9:4

"Then stood up upon the stairs of the Levites, Jeshua, and Bani, Kadmiel, Shebaniah, Bunni, Sherebiah, Bani, [and] Chenani, and cried with a loud voice unto Jehovah their God." — Nehemiah 9:4 (ASV)

Then stood up upon the stairs of the Levites
On an ascent; an elevated place where the Levites used to stand when they sang at the time of sacrifice, and where they might be seen and heard by the people:

Jeshua and Bani, Kadmiel, Shebaniah, Bunni, Sherebiah, Bani, and
Chenani ;
who seem to be all Levites, see (Nehemiah 8:7) ,

and cried with a loud voice to the Lord their God ;
praying with great fervency, and making bitter lamentation for the sins of the people and their own.
