Ezra 10:16-17 TMB

16 And the children of the captivity did so. And Ezra the priest, with certain chief of the fathers, were separated according to the house of their fathers, and all of them by their names. And they sat down on the first day of the tenth month to examine the matter,
17 and they made an end with all the men who had taken foreign wives by the first day of the first month.
