The Same Thing Again, but This Time, Hengel

I'm still stuck on the same issue, and I just want to add a brief comment from a distinguished NT scholar.

Martin Hengel, The Septuagint as Christian Scripture: Its Prehistory and the Problem of Its Canon (Baker, 2002), p. 44:

"In contrast, only fragments of Aquila were found in the Cairo Geniza."

The context of this statement makes it clear that Hengel is thinking of these Aquilanic fragments as Jewish.
