7137. Whom Pharaoh's taskmasters had set over them. That this signifies those who were injected by the infesters, is evident from the signification of "being set over them," as being to be injected, because done by injection (of which in what follows); and from the signification of "taskmasters," as being those who infest (see n. 7111). How this is cannot be known except from experience with such in the other life. It was said above that by "taskmasters" are signified those who most closely infest, and by "officers" those who most closely receive and communicate (n. 7111); they who thus receive and communicate are simple, upright spirits, who are of especial service for such a use; these spirits, by means of arts known only in the other life, are injected by the infesters toward the society with which they thus procure for themselves communication; and this is effected by those who infest and are signified by the "taskmasters;" thus the hells have communication on their side, and they who are being infested on theirs. That this is the case, I have seen a hundred times, if not a thousand, and have also experienced. From all this it is evident that what is signified by these words in the internal sense cannot be known except from experience concerning such things in the other life.
