Redistribution of Population
“Now that the wall has been completed, it occurs to Nehemiah that the city is too large for the number of people inhabiting it; it would take a larger population to defend it properly and to maintain it. Therefore Nehemiah first reviews the record of the initial group of exiles to return and then devises a plan by which 10 percent of the population of Judah and Benjamin will be asked to move into Jerusalem.”
