Arcana Coelestia # 4938
4938. The ones who in the Grand Man correspond to the feet, soles, and heels are those who are natural, which is why in the Word natural things are meant by 'the feet', 2162, 3147, 3761, 3986, 4280. By 'the soles' lower natural things are meant, and by 'the heels' lowest natural, 259. In the Grand Man celestial things constitute the head, spiritual ones the body, and natural ones the feet; they exist in this consecutive order. In addition, celestial things, which are the highest, are ringed about by spiritual ones, which are in the middle; and spiritual things are ringed about by natural, which are lowest ones.
Zechariah 14:5-7
5
You shall flee by the valley of my mountains; for the valley of the mountains shall reach to Azel; yes, you shall flee, just like you fled from before the earthquake in the days of Uzziah king of Judah. Yahweh my God will come, and all the holy ones with you.

It will happen in that day, that there will not be light, cold, or frost.
7
It will be a unique day which is known to Yahweh; not day, and not night; but it will come to pass, that at evening time there will be light.
