And I looked, and, behold, a whirlwind came out of the north, a great cloud, and a fire infolding itself, and a brightness was about it, and out of the midst thereof as the color of amber, out of the midst of the fire.
Ezekiel’s vision begins with a distant storm coming from the north to the south including a cloud and a flashing fire—probably lightening. This phenomena is known to scholars as a “storm theophany,” that is to say, a manifestation of God (theophania) in (or as) a storm.
It is important to note that at the time of his vision Ezekiel is in Mesopotamia on the Chebar River (1:3), a tributary to the Euphrates. The appearance of the storm from the north may be present an indirect indication that it is meant to come from Jerusalem, since at the time of Ezekiel communication between Mesopotamia was not direct from east to west (across the Syrian desert), but travelers would go north and then south, a longer but much easier root. More on the implications of this later. Another way to read “from the north” is from ṣāfôn, which does mean north, but is also the name of the sacred mountain of the Canaanites. Thus, the storm may be coming from the mountain of the gods.
Storm theophanies are quite common in the Bible, most prominent in Ex 19, where a God appears in a storm on Mt. Sinai (e.g. Nah 1:3; See Anchor Bible Dictionary “Theophany in the Old Testament”). The appearance of God in a cloud is also a common motif (eg. Ex 24:15-20, 40:34-38, Num 9:15-23, etc.), and is related to the appearance of God in a cloud at the Transfiguration of Jesus.
The cloud of the storm theophany is symbolically reproduced in the Temple by the burning of incense, so that God appears in the Holy of Holies “in the cloud upon the mercy seat” (Lev 16:2, 12-13). The important point to note here is that in the Temple or outside of the Temple, God frequently appears in a cloud, and to enter into the presence of God, one must pass into this cloud, either the cloud of incense in the Temple, or the storm cloud outside the Temple (Ex 24:15-18; Mt 17:5). In the Temple the flashing light or the shinning glory of the Lord (Mt 17:2) the light of the menorah and the burning coals of the incense altar, while the thunder of the storm is the sounding of the trumpets (šōfār) (Ex 19:16-19). Thus, in the Temple context, storm-cloud, lightening and thunder are incense-cloud, menorah/coals and trumpets.
