BDAG Bibliography Expansion: Biblical Studies (25 vols.) includes twenty-five classic works of Biblical research that the editors of the standard Greek-English lexicon for the New Testament considered important for Greek lexicography.

John Oman presents a new theory for understanding the book of Revelation. Dissatisfied with other common means of contextualizing and interpreting this difficult piece of Scripture, Oman instead offers three positive assertions around which he builds his exegesis: the consistency and unity of thought guarantee a unity of authorship, the strength of the influence from the OT prophets, especially Daniel, and finally those things that seem abstractions to us are readily grounded in realities in the Ancient world.
