Four Aramaic targumim (ancient translations) have God, and not just cherubim, taking up residence east of the garden. This is based on a slightly different vocalization of the Hebrew text, which is likely a more original reading than our current biblical text (MT).Could be. That is clearly the interpretation of the Targumim, but I'm not convinced that it was also the sense of the original Hebrew. One weakness of this reading is that the meaning of so many of the suggested parallel passages is also in doubt.
