Thunder
In Exodus 9:23, 29, this signifies truths divine which enlighten and perfect people in heaven, but terrify people in hell. (Arcana Coelestia 7573)
In Psalm 29:3, this signifies the Word in its power. (Doctrine Regarding Sacred Scripture 18[4])
When the Lord speaks through the heaven, it descends into the lower spheres and is heard as thunder. As He speaks through the whole of heaven at once, the sound is called 'seven thunders' in Revelation 10. 'Seven' signifies all, everything, and wholeness. This is why 'thunder' signifies instruction and perception of truth, and in this instance, the revealing and manifestation of truth. A voice from heaven is heard as thunder when it comes from the Lord, which can be seen in John 12:28-30, Job 37:4-5, 2 Samuel 22:14, Revelation 14:2, and Psalms 81:8. 'Great thunder,' as in Revelation 14:2, signifies the divine good of divine love.

Job 37
1
"Yes, at this my heart trembles, and is moved out of its place.
2
Hear, oh, Hear the noise of his voice, the sound that goes out of his mouth.
3
He sends it forth under the whole sky, and his lightning to the ends of the earth.
4
After it a voice roars. He thunders with the voice of his majesty. He doesn't hold back anything when his voice is heard.
5
God thunders marvelously with his voice. He does great things, which we can't comprehend.
6
For he says to the snow, 'Fall on the earth;' likewise to the shower of rain, and to the showers of his mighty rain.
7
He seals up the hand of every man, that all men whom he has made may know it.
8
Then the animals take cover, and remain in their dens.
9
Out of its room comes the storm, and cold out of the north.
10
By the breath of God, ice is given, and the breadth of the waters is frozen.
11
Yes, he loads the thick cloud with moisture. He spreads abroad the cloud of his lightning.
12
It is turned around by his guidance, that they may do whatever he commands them on the surface of the habitable world,
13
Whether it is for correction, or for his land, or for loving kindness, that he causes it to come.
14
"Listen to this, Job. Stand still, and consider the wondrous works of God.
15
Do you know how God controls them, and causes the lightning of his cloud to shine?
16
Do you know the workings of the clouds, the wondrous works of him who is perfect in knowledge?
17
You whose clothing is warm, when the earth is still by reason of the south wind?
18
Can you, with him, spread out the sky, which is strong as a cast metal mirror?
19
Teach us what we shall tell him, for we can't make our case by reason of darkness.
20
Shall it be told him that I would speak? Or should a man wish that he were swallowed up?
21
Now men don't see the light which is bright in the skies, but the wind passes, and clears them.
22
Out of the north comes golden splendor. With God is awesome majesty.
23
We can't reach the Almighty. He is exalted in power. In justice and great righteousness, he will not oppress.
24
Therefore men revere him. He doesn't regard any who are wise of heart."
