Apocalypse Explained # 651
651. And shall overcome them, and kill them.- That this signifies the destruction thence of all the good and truth of the church, is evident from the signification of overcome and killing the two witnesses, as denoting to destroy those things which the two witnesses signify, which are the good of love and of charity, and the truth of doctrine and of faith. That the affections of the natural man separated from the affections of the spiritual man, which are evil desires of every kind arising from infernal loves, will destroy those things, is signified by the beast coming up out of the abyss; that it was predicted that this will come to pass at the end of the church, when the Last Judgment takes place, has been stated above. To kill, in the Word, signifies to kill spiritually, which is here to destroy the good of love and truth of doctrine, as may be seen above (n. 315).
Exodus 23:28-30
28
I will send the hornet before you, which will drive out the Hivite, the Canaanite, and the Hittite, from before you.
29
I will not drive them out from before you in one year, lest the land become desolate, and the animals of the field multiply against you.
30
Little by little I will drive them out from before you, until you have increased and inherit the land.
