8106. By day in a pillar of cloud. That this signifies that when there was a state of enlightenment it was tempered by obscurity of truth, is evident from the signification of “by day,” or “in the day,” as being in a state of enlightenment; for the times of day, as morning, noon, evening, and night, correspond to the various degrees of enlightenment which belong to intelligence and wisdom in the other life (see n. 5672, 5962, 6110); whence “day” denotes a state of enlightenment or clear perception, and “night” a state of no enlightenment, or of obscure perception (n. 7680); and from the signification of “cloud,” as being obscurity of truth, because a cloud takes away the brightness of light from the sun, and also tempers it.

[2] In the Word throughout it is said that Jehovah appeared “in a cloud,” and that He was “girded with a cloud,” also that “beneath His feet was a cloud;” in which passages by “cloud” is meant obscurity of truth, specifically, the literal sense of the Word, for relatively to the internal sense this sense is obscurity of truth (see the preface to Genesis 18; also n. 4391, 5922, 6343, 6752). This was signified by the “cloud” when the Lord was seen by Peter, James, and John in glory (Luke 9:34); when from Mount Sinai by the people; and when by Moses upon his entering to Him there (Exodus 19:9; 20:18; 24:15-18; 34:5); and also by the circumstance that the Lord so often said that He “would come in the clouds of heaven” (Matthew 24:30; 26:63-64; Mark 13:26; 14:61-62; Luke 21:27).

[3] The literal sense of the Word is called a “cloud,” because the internal sense, which is called “glory,” cannot be comprehended by man, except one who is regenerated, and is also enlightened. If the internal sense of the Word, or truth Divine in its glory, were to appear before a man who is not regenerated, it would be like thick darkness, in which he would see nothing at all, and by which he would also be blinded, that is, would believe nothing. From all this it can be seen what is signified by a “cloud by day,” namely, obscurity of truth; and when the Word is treated of, the literal sense.

[4] It is said “in a pillar of cloud and of fire,” because by “a pillar” is signified a prop which supports (see Jeremiah 1:18 , Psalms 75:3 , Revelation 3:12; Job 9:6); and it is predicated of the natural, because the natural is like a prop or base to the spiritual; for the spiritual closes in the natural, and there rests. Hence it is that the feet of the angel descending from heaven appeared “as pillars of fire” (Revelation 10:1); for by “feet” is signified the natural (see n. 2162, 3147, 3761, 3986, 4280, 4938-4952, 5327, 5328).

3761. And Jacob lifted up his feet. That this signifies the elevation of the natural, is evident from the signification of “lifting up,” as being elevation; and from the signification of the “feet,” as being the natural, concerning which in what follows. The elevation here signified is that treated of in this chapter, which is from external truth to internal good. In the supreme sense it is shown how the Lord elevated His natural even to the Divine, according to order, by ascending from external truth through the degrees to internal good; and in the representative sense, how the Lord makes new the natural of man when He regenerates him, according to a similar order. That the man who is being regenerated in adult age advances according to the order described in the internal sense in this and the following chapters, is known to few, for the reason that few reflect upon it, and also that few at this day can be regenerated. For these are the last times of the church, when there is no longer any charity, consequently not any faith; and this being the case, it is not even known what faith is, although it is on the lips of all that man is saved by faith. Still less is it known what charity is; and as these two are known merely as terms, and are unknown in respect to their essence, it is on this account said that few can reflect upon the order according to which man is made new, or is regenerated, and also that few can be regenerated.

[2] Because the natural is here treated of, and this is represented by Jacob, it is not said that he “arose,” and went to the land of the sons of the east, but that he “lifted up his feet.” Both expressions signify elevation (that “arising” has this signification may be seen above, n. 2401, 2785, 2912, 2927, 3171). But the reason why it is here said, “he lifted up his feet,” is that this is said with respect to the natural; for “feet” signify the natural (n. 2162, 3147). That “feet” signify the natural, or natural things, comes from the correspondence with the Grand Man which has been spoken of at the close of the preceding chapters, in which Grand Man they who belong to the province of the feet are those who are in natural light and but little in spiritual; consequently the parts under the feet, as the soles and the heels, signify the lowest natural things (see n. 259); and hence the shoe, which is also occasionally mentioned in the Word, signifies the corporeal natural which is the ultimate (n. 1748).
