YHWH's Kavod

The kavod...is a luminous manifestation by which God descends to earth and is made visible. The kavod resides in the Holy of Holies of the Tabernacle and the Jerusalem Temple. It is the precursor of the shekhinah, or Divine Presence, of later Jewish sources, but is not entirely identical in conception.
--Victor Hurowitz, Understanding the Priestly Source, Bible Review

An earlier, more primitive concept of Yahweh's immanence? I've never heard of the kavod before. I know the shekinah concept was fully articulated in Rabbinic times, but always thought the concept reached back into ancient Israelite history. Well, there's one more thing to learn about. Fortunately, it's things like this that get me excited.
