These are scholarly, conservative commentaries with helpful insights throughout. As far as I can tell, these volumes are premillennial and dispensational in orientation (which I share), but worthwhile for those from other theological persuasions as well. Each commentary discusses all relevant Hebrew and Greek words in depth, in every verse, utilizing sound exegetical principles. I would recommend these for serious students of the Word. I have even used the Jonah volume in a 2nd year Hebrew exegesis class. The discussions of the lexical and contextual components of each verse are handled with scholarly thought and care. Highly recommended.
