366. That they should slay one another, signifies the falsification or extinction of truths. This is evident from the signification of "slaying," as meaning the extinction of truths; for "to slay" in the Word signifies to slay spiritually, that is, to slay the spiritual part of a man or his soul, which is to extinguish truths. It also means to falsify, because when truths are falsified they are also extinguished; for falsification produces a different understanding of truths, and truth is true to everyone according to his understanding of it; for the love and principle that rule in man draw and apply all things to themselves, even truths themselves; consequently when the love is evil, or the principle is false, then truths are infected with the evil of the love or the falsity of the principle, and thus are extinguished. This, therefore, is what is here signified by "they should slay one another." That this takes place when there is no good with man, and especially when there is no good in the doctrine of his church, is evident from the preceding words, where it is said, "When he had opened the second seal there went forth a red horse; and to him that sat upon him it was given to take peace from the earth;" which signifies a second state of the church when the understanding of the Word is destroyed in respect to good, which is the source of dissensions in the church (of which see above, n. 361, 364, 365).

[2] That the understanding of the Word, or what is the same, the understanding of the truth, is destroyed when there is no good with man, that is, when there is no love to the Lord and charity towards the neighbor, may be seen above n. 365; for good with man, or what is the same, love with him, is the fire of his life, and truth with him, or the faith of truth, is the light therefrom; consequently such as the good is, or such as the love is in man, such is truth, or such the faith of truth in him. From this it can be seen that when evil or an evil love is with man there can be no truth or faith of truth with him; for the light that goes forth from such fire is the light that those have who are in hell, which is a fatuous light like the light from burning coals, which light, when light from heaven flows in, is turned into mere thick darkness. Such also is the light that with the evil, when they reason against the things of the church, is called natural light [lumen].

[3] That they would falsify and thereby extinguish truths is meant also by the Lord's words in Matthew:

Jesus said to the disciples, The brother shall deliver up the brother, the father the son; children shall rise up against parents, and cause them to be put to death (Matthew 10:21).

And in Luke:

Ye shall be delivered up by parents, and brethren, and kinsfolk, and friends; and some of you shall they cause to be put to death (Luke 21:16).

"Parents," "brethren," "children," ["kinsfolk, "] and "friends," do not mean here parents, brethren, children, kinsfolk, friends, nor do "disciples" mean disciples, but the goods and truths of the church, also evils and falsities; it is also meant that evils would extinguish goods and falsities truths. (That such is the signification of these words, see Arcana Coelestia 10490.)

4742. 'The tunic of various colours that was on him' means the nature of the appearances which is determined by that of the truths derived from good. This is clear from the meaning of 'the tunic of various colours' as appearances of truth by which the spiritual of the natural is recognized and distinguished, dealt with in 4677, here therefore the nature of those appearances; and for this reason the word 'tunic' is used twice - 'they stripped Joseph of his tunic, the tunic of various colours'. The fact that the nature of these appearances is determined by that of the truths derived from good may be known from appearances of truth when these are manifested visually in the light of heaven, that is, in the next life. There no other light exists than that which comes from the Lord by way of heaven and which emanates from His Divine Truth; for this appears before the eyes of the angels as light, 2776, 3190, 3195, 3222, 3339, 3340, 3636, 3643, 3993, 4302, 4413, 4415. This light varies with each angel, depending on his reception of it. Angels' entire thought is formed by the variegation of that light, as also is man's thought, though he is not conscious of this because in man's case that light falls onto material images or ideas present in his natural or external man which are formed from the light of the world.

Consequently in his case the light of heaven is dimmed to such an extent that he scarcely knows that the light and sight in his understanding are a product of the light of heaven. But in the next life when the sight of the eye is no longer reliant on the light of the world but on that of heaven it is then obvious that his thought is formed from the latter.

[2] When this light passes from heaven into the world of spirits it manifests itself there in the form of various colours, the beauty, variation, and loveliness of these colours being immensely superior to the colours produced by the light of the world; see what has already been presented from experience regarding colours, in 1053, 1624, 3993, 4530, 4677. Because colours in the next life are formed from the light of heaven they are in origin nothing else than appearances of truth derived from good. The source from which truth shines is not truth itself because by itself alone it does not possess any flame; rather, good is the source of it since this is like the flame from which light shines. The nature of good therefore determines the nature of the truth that appears from it, and the nature of the truth is the same as that of the good from which it shines. From this one may see what is meant in the internal sense by 'the tunic of various colours' - that the nature of the appearances is determined by that of the truths derived from good; for as shown already, 'Joseph', to whom the tunic belonged, represents Divine Truth.
