A new collection of articles on Philo and the New Testament was published most recently by Brill:
Peder Borgen, Iluminations by Philo of Alexandria. Selected Studies on Interpretation in Philo, Paul, and the Revelation of John. Edited by Torrey Seland (Studies in Philo of Alexandria 12: Leiden; Brill, 2021).
The volume contains 17 articles, all previously published in various Journals and Festschriften, and not always easy to track or find. Hence this new volume brings some of the most recent studies by prof. P. Borgen. David E. Aune introduces the volume by summarizing each article in the collection.
