Ezra is astonished that his people have been marrying women who aren't Jews, so he assembles everyone and tells them to abandon their 'strange' families.
An enemy catches wind of the building of a house for God and sends the Jews a cease and desist letter so they have to find proof that King Cyrus told them they could build it. Sounds like a typically bureaucratic planning committee to me.
And this Ezra guy turns up 7 chapters in to his own book.
The Jews are released from their captivity in Babylon - and everyone who returned to Judah is listed in full boring detail. They return to Jerusalem to build a new house for God, and they're very happy about it too.
