Jamieson, Fausset and Brown on Ezra 10:5-8

5-8. Then Ezra ... went into the chamber of Johanan--At a private council of the princes and elders held there, under the presidency of Ezra, it was resolved to enter into a general covenant to put away their foreign wives and children; that a proclamation should be made for all who had returned from Babylon to repair within three days to Jerusalem, under pain of excommunication and confiscation of their property.
