The transmission of the Blessing of Isaac, Jacob and Moses by Hippolytus

In the Patrologia Orientalis 27, fascicle 1-2, a text called The blessing of Jacob appears.   It is a commentary on Genesis 49.  This is given in Greek, but also in Armenian and Georgian.  A French translation is included.  The Greek text seems to have been discovered relatively recently, and contains glosses at some points, as the Armenian shows.  There is also a text called The blessing of Moses printed, which is extant only in Armenian and Georgian, with a couple of fragments of Greek only.
