Bric-a-brac

As of 8/30/2009, I have completed the reading of Ezra and Nehemiah.

Why was Nehemiah, the cup-bearer to King Artaxerxes, afraid to answer the King when he asked Nehemiah what was troubling him?  The text words the Kings question like this: “Why is your face sad, since you are not sick?  This can only be a sadness of the heart.”

What event at the end of Chronicles sets it apart from Kings?  How does this event affect the tone of Chronicles in comparison to the tone of Kings?

How old was Josiah when he began his 31 year reign over Jerusalem? (8 yrs. old)

King Cyrus ruled which nation?  (Persia)
