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.
