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 the LORD their God.

Then stood up upon the stairs. The scaffolds or pulpits, whence the Levites usually addressed the people. There were probably several placed at convenient distances, to prevent confusion, and the voice of one drowning those of the others.

Cried with a loud voice. Such an exertion, of course, was indispensably necessary, in order that the speakers might be heard by a vast multitude congregated in the open air. But these speakers were then engaged in expressing their deep sense of sin, as well as fervently imploring the forgiving mercy of God, and 'crying with a loud voice' was a natural accompaniment of this extraordinary prayer meeting, as violent gestures and vehement tones are always the way in which the Jews, and other people in the East, have been accustomed to give utterance to deep and earnest feelings.
