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)

440. And they had as king over them the angel of the bottomless pit, whose name in Hebrew is Abaddon, but who in Greek has the name Apollyon. (9:11) This symbolically means that those caught up in falsities springing from lusts, who by a total falsification of the Word destroyed the church, are in a satanic hell.

The angel of the bottomless pit as king does not signify that some angel is king there, but that falsity reigns in it. For a king in its genuine sense symbolizes someone who possesses truths owing to an affection for goodness, and abstractly truth itself (no. 20); and in an opposite sense, therefore, a king symbolizes someone who is caught up in falsities owing to a lust for evil, and abstractly falsity itself. The bottomless pit symbolizes the satanic hell where such people reside (nos. 387, 421). A name symbolizes the character of someone's or something's state (nos. 81, 122, 165).

Abaddon in Hebrew is someone who destroys, or a destroyer, and likewise Apollyon in Greek, and this is falsity of the most fundamental sort, which by a total falsification of the Word has destroyed the church.

Abaddon in the Hebrew text means destruction in the following places:

Your truth in destruction? (Psalms 88:11)

Hell is naked before Him, and destruction has no covering. (Job 26:6)

For it will be a fire that consumes to destruction... (Job 31:12)

Destruction and death say... (Job 28:22)

Elsewhere hell and the devil are called destruction or a destroyer (Isaiah 54:16, Ezekiel 5:16; 9:1, Exodus 12:13), but by using another term.
