The sun is double-faced; one face, of fire, is directed toward the earth, and one of hail, toward heaven, to cool off the prodigious heat that streams from the other face, else the earth would catch afire. In winter the sun turns his fiery face upward, and thus the cold is produced.[103] When the sun descends in the west in the evening, he dips down into the ocean and takes a bath, his fire is extinguished, and therefore he dispenses neither light nor warmth during the night. But as soon as he reaches the east in the morning, he laves himself in a stream of flame, which imparts warmth and light to him, and these he sheds over the earth. In the same way the moon and the stars take a bath in a stream of hail before they enter upon their service for the night.[104] When the sun and the moon are ready to start upon their round of duties, they appear before God, and beseech him to relieve them of their task, so that they may be spared the sight of sinning mankind. Only upon compulsion they proceed with their daily course. Coming from the presence of God, they are blinded by the radiance in the heavens, and they cannot find their way. God, therefore, shoots off arrows, by the glittering light of which they are guided. It is on account of the sinfulness of man, which the sun is forced to contemplate on his rounds, that he grows weaker as the time of his going down approaches, for sins have a defiling and enfeebling effect, and he drops from the horizon as a sphere of blood, for blood is the sign of corruption.[105] As the sun sets forth on his course in the morning, his wings touch the leaves on the trees of Paradise, and their vibration is communicated to the angels and the holy Hayyot, to the other plants, and also to the trees and plants on earth, and to all the beings on earth and in heaven. It is the signal for them all to cast their eyes upward. As soon as they see the Ineffable Name, which is engraved in the sun, they raise their voices in songs of praise to God. At the same moment a heavenly voice is heard to say, "Woe to the sons of men that consider not the honor of God like unto these creatures whose voices now rise aloft in adoration."[106] These words, naturally, are not heard by men; as little as they perceive the grating of the sun against the wheel to which all the celestial bodies are attached, although the noise it makes is extraordinarily loud.[107] This friction of the sun and the wheel produces the motes dancing about in the sunbeams. They are the carriers of healing to the sick,[108] the only health-giving creations of the fourth day, on the whole an unfortunate day, especially for children, afflicting them with disease.[109] When God punished the envious moon by diminishing her light and splendor, so that she ceased to be the equal of the sun as she had been originally,[110] she fell,[111] and tiny threads were loosed from her body. These are the stars.[112] THE FIFTH DAY
