I am interested in the physical circumstances of this "explaining (and translating) of the law."
Traditionally the Hebrews were divided into governable groups of thousands, hundreds, fifties, and tens. Exodus 18:24-27 Jesus divided the 5,000 he fed into groups of hundreds and fifties. Mark 6:39-40
But when it comes to speaking to a large group of people, physical factors enter: echo, volume, background noise, and so on.
Anyone care to comment on how Ezra's reading (and translation) got to each person in the crowd who was listening? How they were arranged, how the voices of the 13 Levites were isolated so no one heard more than one of them at any time, which would have been very confusing?
