9373. Come up unto Jehovah. That this signifies conjunction with the Lord, is evident from the signification of “coming up,” as being to be raised toward interior things (see n. 3084, 4539, 4969, 5406, 5817, 6007), consequently also to be conjoined (n. 8760). That it denotes conjunction with the Lord, is because by “Jehovah” in the Word is meant the the Lord, (n. 1343, 1736, 1793, 2004, 2005, 2018, 2025, 2921, 3023, 3035, 5663, 6280, 6303, 6905, 8274, 8864, 9315). A secret which also lies hidden in the internal sense of these words, is that the sons of Jacob, over whom Moses was the head, were not called and chosen; but they themselves insisted that Divine worship should be instituted among them (according to wh at has been said in n. 4290, 4293); and therefore it is here said, “and He said unto Moses, Come up unto Jehovah,” as if not Jehovah, but another, had said that he should come up. For the same reason in what follows it is said that “the people should not go up” (verse 2); and that “Jehovah sent not His hand unto the sons of Israel who were set apart” (verse 11); and that “the appearance of the glory of Jehovah was like devouring fire on the top of the mountain in the eyes of the sons of Israel” (verse 17); and lastly that Moses, being called the seventh day, “entered into the midst of the cloud.” For by “the cloud” is meant the Word in the letter (n. 5922, 6343, 6752, 6832, 8106, 8443, 8781); and with the sons of Jacob the Word was separated from its internal sense, because they were in external worship without internal, as can be clearly seen from the fact that now, as before, they said, “all the words which Jehovah hath spoken we will do” (verse 3); and yet scarcely forty days afterward they worshiped a golden calf instead of Jehovah; which shows that this was hidden in their hearts while they were saying with their lips that they would serve Jehovah alone. But nevertheless those who are meant by “the called and the chosen” are those who are in internal worship, and who from internal worship are in external; that is, those who are in love to and faith in the Lord, and from this in love toward the neighbor.

'Urim,' as in Isaiah 24:15, signifies the light from the divine truth proceeding from the Lord.

8813. That there were voices and lightnings. That this signifies a Divine state which was revelation, is evident from the signification of “voices” which are sounds of thunders, as being truths Divine; and from the signification of “lightnings,” as being the ruddy glow and brightness of these truths, for truths Divine are bright and glowing from the flame of the light that is from the sun of heaven. Hence it is that by “voices and lightnings” is signified a Divine state in which is revelation; a Divine state, by the descent of such things from heaven; and revelation, by the voices and lightnings being truths Divine. That by “voices” which are of thunders from heaven are signified truths Divine, see n. 7573; and that “lightnings” denote the brightnesses from them which strike upon the internal sight of man, enlightening those who are in truth from good, and confounding those who are in falsity from evil, is evident from passages in the Word where “lightnings” are mentioned, as in David:

The clouds dripped waters, the skies gave forth a voice, and Thine arrows went abroad, the voice of Thy thunder into the world, the lightnings enlightened the world, the earth shook and trembled (Psalms 77:17-18); where “the voice of thunder” denotes truth Divine (n. 7573); “lightnings” denote its brightness; and “the world,” the church; consequently “the lightnings enlightened the world” denotes the enlightening of the church by truth Divine.

[2] In like manner in the same:

His lightnings enlightened the world, the earth shall see and shall fear, the mountains shall melt like wax before Jehovah (Psalms 97:4-5).

What Jehovah willeth, He doeth in the heavens and in earth, in the seas and in all abysses, who maketh the vapors to ascend from the extremity of the earth, He maketh lightnings for the rain (Psalms 135:6-7; Jeremiah 10:13; 51:16); where “lightnings for the rain” denotes the brightness of the truth that comes down from heaven.

In John:

There were lightning, voices, and thunders (Revelation 11:19 16:18); where “voices, lightnings, and thunders” denote truths Divine which enlighten the good and terrify the evil.

[3] In Ezekiel:

The appearance of the living creatures (which were cherubs) was like burning coals of fire, like the appearance of torches, and it went along among the living creatures, so that there was the brightness of fire, and out of the fire went forth lightning. And the living creatures were running and returning according to the appearance of lightning (Ezekiel 1:13-14); where “fire” denotes the good of love, and “lightning going forth out of the fire,” the truth Divine therefrom. The Divine Providence of the Lord, which is truth Divine proceeding from the Divine good of the Lord, is here described by the “cherubs.”

[4] In Daniel:

Behold one clothed in linen, whose loins were girded with gold of Uphaz, and his body was like a tarshish, his face as the appearance of lightning, and his eyes as torches of fire (Daniel 10:5-6).

“The face as the appearance of lightning” denotes the love of truth, because the truth which is from love bears with it a flaming from fire, which flaming is “lightning.”

[5] In Zechariah:

Jehovah shall appear over them, and His arrow shall go forth as the lightning; and the Lord Jehovih shall sound with the trumpet, and shall advance in whirlwinds of the south (Zech. 9:14).

“The arrow which shall go forth as the lightning” denotes truth Divine which reproves and penetrates. That “an arrow” denotes the truth of doctrine, see n. 2686, 2709; thus “an arrow from Jehovah” denotes truth Divine.

[6] In Nahum:

The brightness of a sword, the lightning of a spear, and a multitude of slain (Nah. 3:3).

In Moses:

I will sharpen the lightning of My sword (Deuteronomy 32:41);

denoting the penetration of truth Divine with the evil; “sword” denotes truth fighting (n. 2799, 8294); and “lightning” the brightness of it which strikes upon the intellectual and deprives it of the faculty of seeing truth: in like manner in Ezekiel 21:20-32. From all this it is also evident that by “lightning” is meant truth Divine, as in Matthew 28:3, and in Luke 17:24.
