6657. And it will also join itself to our enemies, and fight against us. That this signifies that so their companions who would occasion evil would be strengthened, is evident from the signification of "joining themselves to," as being to be strengthened, for armies are strengthened when a multitude is joined to them; from the signification of "enemies," as being companions who fight along with them; and from the signification of "fighting against us," as being to occasion evil, for when anyone is fought against, evil is occasioned him insofar as it cannot be resisted. The case herein is this. There is around every man, and also around every good spirit, a general sphere of endeavors from hell, and a general sphere of endeavors from heaven. The sphere from hell is one of endeavors to do evil and to destroy; and the sphere from heaven is one of endeavors to do good and to save (see n. 6477). These are general spheres: in like manner there are particular spheres around each man, for spirits from hell are with him, and also angels from heaven (n. 5846-5866, 5976-5993). From this a man is in equilibrium, and has freedom to think and will evil, and freedom to think and will good.
[2] When therefore the man of the church comes into temptation, which takes place when he is let into his evil, there is then a combat around him between the spirits from hell and the angels from heaven (n. 3927, 4249, 5036), which combat lasts so long as the man is kept in his evil. In this combat it sometimes appears to the spirits from hell that they will conquer, and then they rise up; sometimes that they will be conquered, and then they withdraw, because they then fear that more angels from heaven will join themselves against them, and so that they will be cast down into hell, from which they will no more come out, which also takes place when they have been conquered. This is what is meant by the "prevalence if it grows, and that their companions who would occasion evil would be strengthened."
[3] When the spirits from hell fight against the angels, they are in the world of spirits, and are in freedom there (n. 5852). From all this it can now be seen what is meant in the internal sense by the sons of Israel being so infested and oppressed by the Egyptians, and by their being multiplied the more, the more they were infested; and by Jehovah, that is, the Lord, fighting for them, and restraining the Egyptians by plagues, and at last submerging them all in the sea Suph.
