The following note is slightly abridged from the Edition of Alexandrides of Jerusalem.  “Previous Editions read ἔξ ὄρους φαρὰν κατασκίου δασέος.  This reading is found in Cod. Vat. and other mss. of the Septuagint, but φαράν is omitted in the Aldine and many other copies nor was it read in the mss. of the Sept. in Jerome’s time, as is clear from his comments on the passage.  In the mss. of Cyril, Ottob. R.C.V. Monac. I. and II. it is wanting.  Paran is the name of the desert towards the S. of Palestine lying between it and Egypt (Gen. xxi. 21; Num. i. 12).  There was also a Mount Paran (Deut. xxxiii. 2).  But since Cyril applies the prophecy to Bethlehem, and the “shady thickly-wooded mountain” of Habakkuk is identified with “the plains of the wood” of David, we may safely conclude that Cyril did not read φαράν in his copies of the Septuagint, nor write it in his Lecture:  but the reading crept in from the later copyists, accustomed to the reading φαράν in the Septuagint.”
