8819. And Mount Sinai smoked, the whole of it. That this signifies the appearing of celestial good in the greatest obscurity, is evident from the signification of "Mount Sinai," as being celestial good (see just above, n. 8818); and from the signification of "smoking," as being an appearing in obscurity. By obscurity is meant the obscurity of faith, such as is theirs who are of the spiritual church as compared with the faith of those who are of the celestial church (n. 2708, 2715, 2718, 2831, 2935, 2937, 3241, 3833, 6289). By the greatest obscurity, which is signified by "Mount Sinai smoked, the whole of it," and by what is said just below, that "the smoke thereof ascended as the smoke of a furnace," is meant that obscurity in which was the Israelitish nation, before whom the appearing took place; for Jehovah or the Lord appears to everyone according to his quality (see n. 8788, 8814), thus as love and as the light of truth to those who are in good, but as an enemy and avenger to those who are in evil. That so did He appear to the Israelitish people, is also evident from other passages in Moses:
The appearance of the glory of Jehovah was like devouring fire on the top of the mountain before the eyes of the sons of Israel (Exod. 24:17).
Ye came near and stood under the mountain; when the mountain burned with fire unto the heart of heaven, darkness, and cloud, and thick darkness. And Jehovah spake unto you out of the midst of the fire (Deut. 4:11, 12; 5:22).
It came to pass, when ye heard the voice out of the midst of the darkness, and the mountain did burn with fire, that ye came near unto me, and ye said, why shall we die? because this great fire will devour us: if we hear the voice of Jehovah our God anymore, we shall die (Deut. 5:23-25).
 The reason for this is that no one can see God otherwise than from such things as are in himself, so that he who is in hatred sees Him from hatred, he who is in unmercifulness sees Him in unmercifulness; and on the other hand, they who are in charity and mercy see Him from, and thus in, charity and mercy. The case herein is as it is with the rays of light, which when they fall into ugly forms are turned into ugly colors; but when they fall into beautiful forms are turned into beautiful colors. (That "smoke" denotes the obscurity of truth and also the thick darkness which is of falsity, is evident in Isa. 9:18, 19; 34:9, 10; in Joel 2:30, 31; in Hos. 13:3; and in Rev. 9:17, 18; 18:18; 19:3.)
