Charles Ellicott Commentary Nehemiah 8:2

"And Ezra the priest brought the law before the assembly, both men and women, and all that could hear with understanding, upon the first day of the seventh month." — Nehemiah 8:2 (ASV)

Both of men and women, and all that could hear with understanding. —Men, women, and children who had reached years of discretion.

Upon the first day of the seventh month. —As the seventh was the most important month, in a religious sense, so the first day, the Feast of Trumpets, was the most important new moon (Leviticus 23:24).
