Professor William Hamblin of Brigham Young University has begun posting notes on temple themes in the book of Isaiah on his blog: http://hamblinofjerusalem.blogspot.com/.  He has covered the first three chapters of Isaiah so far and has shared some wonderful insights, drawing from his vast knowledge of the temple and ancient Near Eastern history, culture, and religion. Definitely worth checking out! You can also access the notes on Scribd here.

Hamblin has just recently returned from an extended stay in Jerusalem and has shared loads of photos, videos, and blog posts from his stay there, which are also very much worth your time to see.  For example, check out this cool 360 photo of the Western Wall that he posted.
