Midrasz do Wyjścia 40:4

All the great luminaries of the stars are situated in the south except Ursa Major, which is placed in the north. All the Mazziḳin which move in the firmament and the angels who fell from their holy place (even) from heaven, (when) they ascend to hear the (Divine) Word behind the veil they are pursued with a rod of fire, and they return to their place.
