6423. And he shall sit in the strength of his bow. That this signifies that he is safe by means of the fighting truth of doctrine, is evident from the signification of "sitting," as being to be safe, for he who sits in the strength of his bow is safe; and from the signification of a "bow," as being doctrine (see n. 2686, 2709). The strength of doctrine is truth, for doctrine in which there is no truth is of no avail (that to truth belong power and strength, see above, n. 878, 3091, 4931, 4934, 4937, 6344). The reason why truth is strong, is that good acts through truth; for good is of such a nature that nothing of evil or of falsity can approach it, thus none of the infernal crew, who flee far away when good approaches, or an angel who is in good. But in order that good may fight with that crew which is with man from hell, and protect him in every way, and also protect the spirits who arrive from the world, and likewise those who are in the lower earth, it acts through truth, for in this way it can approach them.
 How much power there is in truth has been made evident to me by what it has been given me to see in the other life. A certain spirit who was in natural truth, because during his life in this world he had been a just man, passed through a number of hells, and spoke with me from thence, and described them; he was in power and strength so great that the infernal spirits could not at all infest him, so that he passed safely from one hell into another, which is quite impossible for those who are not in truth. From all this it is evident that by "sitting in the strength of a bow" is signified to be safe by means of the truth of doctrine: that it is by truth fighting, follows from what goes before, where it is said that "the archers shoot at him and hate him."
