I had never read Rata before, but I will look for him in the future. This was the best of several commentaries I've read on Ezra & Nehemiah. Deep, but not unnecessarily technical. Highly readable & applicable.
This commentary is in depth without being overly technical & though the language was a little dated, it was still clear & usable by those of us without extensive knowledge of biblical languages. Don't let its age fool you, this commentary has stood the test of time!
