Ghassan Khalaf in his book “The Adnominal Genitive in the Pauline Corpus”, talking of the Hebrew Genitive states on page 94
He also cites Zerwick and Turner to this effect.This kind of adjectival genitive is called the “Hebrew” genitive, because it is rarely found in classical Greek. Its function and usage are almost exclusively Hebrew… Blass and Debrunner note, “Hebrew usage is thus reflected, in that this construction compensates for the nearly non-existent adjective. Classical Greek exhibits very sparse parallels in poetry only”… This is not to say that the usage is absolutely foreign to Greek: the usage is possible, but unusual in earlier periods of Greek until it is brought to the forefront in Hellenistic Greek by usage paralleled in Hebrew
Any thoughts on this from our classists or those familiar with secular Hellenistic Greek where a Hebraic influence is less likely? I am planning on keeping my eye out for it in Lucian’s works as I continue through those as well as some other secular texts I am working through.
