According to Nehemiah, the leaders of the Levites, like Hashabiah and Sherebiah, were responsible for singing and giving thanks to God, just as David had instructed long ago. They took turns to make sure there were always praises and thanks being given.
Nehemiah 12:24: And the chief of the Levites: Hashabiah, Sherebiah, and Jeshua the son of Kadmiel, with their brethren over against them, to praise [and] to give thanks, according to the commandment of David the man of God, ward over against ward.
This verse states that "God is not the author of confusion, but of peace," whereas Nehemiah 12:24 emphasizes structured oversight, suggesting a form of ordered worship rather than peace or avoidance of confusion.
1 Corinthians 14:33: For God is not [the author] of confusion, but of peace, as in all churches of the saints. [confusion: Gr. tumult, or, unquietness]
