Ezra 10:16

And this was the manner in which the children of the captivity acted. There were set apart Esdras the priest, and head men of families for every house, and all who were named were to return on the first day of the tenth month, to make strict inquiry into this matter.

And the children of the captivity did thus: and Esdras the priest, and heads of families according to their house were separated, and all by their names, for they returned in the first day of the tenth month to search out the matter.
