Hi Kat,
Thanks for the historical perspective from the article, I would like to add that the lives of Moses and Ezra were separated by around a thousand years so obviously this was not written from first hand experience/witness. Even as Ezra had edited earlier writings from others it (the editing) was directed from above (as I am certain you already know and believe).
2Pe 1:21 For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.
I tend to see the Word not as a compilation of different men/women writing about things they necessarily saw and experienced but rather a seamless communication from the Spirit of God to those whom He has chosen to have eyes to see and ears to hear. It is full of riddles and parables that seem foolish to the wise of the world but infinitely deep to those who desire to be "fools for Christ!"
1Co 3:18 Let no man deceive himself. If any man among you seemeth to be wise in this world, let him become a fool, that he may be wise.
Peace,
Joe
