NOTES:

1 Source references within chevron brackets, e.g. <1033>, refer to numbered paragraphs in "The Annals Of The World" revised by Larry and Marion Pierce, ISBN: 089051-360-0
2 Authorising Ezra to administer God's law from Jerusalem re-instated Israel as one nation and restored Jerusalem to God's intended role as the nation's capital city.
3 Some date Artaxerxes rule from when he became co-regent. However this is unlikely because he is called "king of kings"  in. Ezra 7:12 and has seven councillors. Ezra 7:14,15.
4 However God had promised to be a wall of fire around Jerusalem. Zechariah 2:4-5.
