In Genesis 14:1, kings signify apparent goods and truths having the upper hand. In the next verse, they stand for the dominant evils and falsities against which the Lord fought as he passed He grew up on Earth.

In Genesis 14:3, we see that these evils and falsities were unclean; and in Genesis 14:4, that they burst forth later. (Arcana Coelestia 1661-1664).

In Genesis 14:14-15, this signifies that the Lord gained victory over them the evils represented earlier in the chapter. (Arcana Coelestia 1711-1715)

In Isaiah 33:17, a king signifies seeing genuine truth. (Apocalypse Explained 304[31])

In Revelation 9:11, a king signifies one who is in truth from an affection for what is good, and abstractly that truth itself -- here, in the opposite sense. (Apocalypse Revealed 440)

1624. The form of one of the large rainbows was shown to me, so that from it I could get to know what their smallest forms were like. It was a pure white light with a kind of border, in the middle of which was a dark object as if made of earth. This was surrounded by an extremely luminous halo, itself variegated and divided up by another luminescence that had yellow dots like tiny stars. Additional variegations were produced by flowers of different colours entering the luminous area. The colours of these flowers emanated not from a white light but from a flame-like one. All of these appearances were representative of celestial and spiritual things. All the colours that are seen in the next life represent that which is celestial or spiritual. The colours emanating from the flame-like light represent things that belong to love and the affection for good, whereas colours emanating from the white light represent those that belong to faith and the affection for truth. These are the sources of all colours in the next life, and they are therefore so resplendent that the colours of this world cannot compare with them. Colours also exist there which are never seen in this world.
