Yeah. Mainly. But in that context it wasn't limited to the geography of modern day Greece, but to the whole empire from Western Asia and North Africa to Western Europe. Greeks didn't exist in a vacuum. Arguably much of the foundations of Hellenic philosophy are rooted in Vedism and Buddhism by way of Alexander's campaign into India and the philosophers (eg. Pyrrho) he brought with him.

Largely it was Greek focused also because the literature in question was hoarded away in church libraries by scholars who almost exclusively spoke Greek and Latin at the time. Even the earliest complete copies of the OT and NT were written in Greek. The Torah as such didn't even exist in writing until the 2nd-3rd century CE (ie. Septuagint), and the earliest evidence of it's practice whatsoever goes back to at most 150 BCE. To say nothing of the hermeneutics which are practically indistinguishable from Platonism in one form or another.
