572. That they should kill the third part of men, signifies of depriving themselves of all understanding of truth, and thus of spiritual life. This is evident from the signification of "to kill," as being to deprive of spiritual life (See above, n. 547); and from the signification of "men," as being the understanding of truth (See also above, n. 546, 547); "the third part," in reference to truths, means all (See above, n. 506); so here "to kill the third part of men" signifies the deprivation of all understanding of truth. It means to deprive themselves, because those who become sensual through evils of life and falsities of doctrine deprive ¹ themselves, by reasonings from fallacies, of the understanding of truth, but not others, except such as are sensual. They thus deprive themselves of spiritual life, because man has spiritual life through his understanding, for he becomes a spiritual man in the measure in which his understanding is opened and permits itself to be enlightened by means of truths. But it is by means of truths from good that the understanding is opened, not by means of truths without good; for man thinks truth so far as he lives in the good of love and charity. Truth indeed is the form of good, and all good with man is of his will, and all truth is of his understanding; therefore the good of the will presents its form in the understanding, and the form itself is thought from the understanding which is from the will.

Notes de bas de page:

1866. 'From the river of Egypt to the great river, the river Phrath' means the extension of spiritual and celestial things, 'to the river of Egypt' being the extension of spiritual things, 'to the river Phrath' the extension of celestial things. This is clear from the meaning of 'the river of Egypt' and from the meaning of 'the great river' or the Euphrates. That these rivers mean the extension of spiritual and celestial things becomes clear from the meaning of 'the land of Canaan' as the Lord's kingdom in heaven and on earth, in which kingdom there is nothing else than the spiritual things of faith and the celestial things of mutual love. Consequently nothing else can be meant by the borders of the land of Canaan than the extension of those things. For what the land of Canaan is, what the river of Egypt is, and what the great river, the Euphrates, is, the inhabitants of heaven do not know at all. Indeed they do not know what the borders of any land are; but they do know what the extension of spiritual and celestial things is, and the range and limits of the states belonging to them. These are the things which those in heaven have in mind when such things in the letter are read by man, so that the letter and its historical sense which has served as a basis for heavenly ideas disappears.

[2] The reason why 'the river of Egypt' means the extension of spiritual things is that 'Egypt' means factual knowledge which, together with the rational concepts and the intellectual concepts which a person has, constitute spiritual things, as stated already in 1443 and elsewhere in this volume. And as to why in the internal sense 'Egypt' means factual knowledge, see 1164, 1165, 1186, 1462. That 'the river Euphrates' means the extension of celestial things becomes clear from the lands which that river bounded and marked off from the land of Canaan, and by which in many other places facts and the cognitions of celestial things are meant. Here however because it is called 'the river', and 'the great river', they are nothing other than celestial things and the cognitions of them, for 'the great river' and greatness are used in reference to these.
