So the exiles did as was proposed. Ezra the priest selected men who were family heads, one from each family division, and all of them designated by name. On the first day of the tenth month they sat down to investigate the cases (NIV)
Then the returned exiles did so. Ezra the priest and certain heads of fathers' houses were selected, according to their fathers' houses, each of them by name; and they sat down on the first day of the tenth month to investigate the matter. (AMP)
And the children of the captivity did so. And Ezra the priest, with certain chief of the fathers, after the house of their fathers, and all of them by their names, were separated, and sat down in the first day of the tenth month to examine the matter. (KJV)
