Interesting post. I’ve always simply identified the Shekinah Glory as a manifestation of His indwelling.
One example would be the burning bush, another the pillar of fire advancing in the desert before the Hebrew nation, another is the phenomenon of halo as depicted in many medieval artistic renderings, as well as the cloud surrounding the Tabernacle when He was present within.
That is the projected interpretation used by many Christian ministers.
The term, however, does not appear in the Bible and since most of the New Testament writers were Jewish one could reasonably assume they had some knowledge of it. Because Aramaic was in common use during the time of Christ the word was allegedly understood and used by the Jewish population. There is no record that I've come across anyway, that Jesus or his Apostles ever used the term. Please keep in mind, I am no scholar.
