Apocalypse Explained # 387
387. And with death, signifies the consequent extinction of spiritual life. This is evident from the signification of "death," as being the extinction of spiritual life (See above, n. 78, 186). That this is what "death" here signifies is evident from the series of things in the internal sense; for it is said that "there was given unto them power to kill with sword, with famine, and with death;" and "sword" signifies falsity destroying truth, "famine" the deprivation of the knowledges of truth and good; thence "death" signifies the extinction of spiritual life; for where falsity reigns, and where there are no knowledges of truth and good, there is no spiritual life, for spiritual life is acquired by means of the knowledges of truth and good applied to the uses of life. For man is born into all evil and falsity from evil; he is therefore born also into an entire ignorance of all spiritual knowledges; therefore in order that he may be led away from the evils and consequent falsities into which he is born, and be led into the life of heaven and be saved, he must needs acquire the knowledges of truth and good, by means of which he can be led into spiritual life and become spiritual. From this series of things in the internal sense it is evident that "death" here signifies the extinction of spiritual life; this is meant, too, by spiritual death.
Arcana Coelestia # 1996
1996. 'I will make My covenant between Me and you' means the union of the Internal Man, which was Jehovah, with the Interior Man. This is clear from the meaning of 'a covenant' as a joining together, for as often as a covenant between Jehovah and man is mentioned in the Word, nothing else is meant in the internal sense by a covenant than the Lord's being joined to man. The covenants made so many times between Jehovah and the descendants of Jacob had no other representation. As this point has been confirmed in Volume One, in 665, 666, 1023, 1038, 1864, it would be superfluous to do so again here. The Lord's Internal Man was Jehovah because He was conceived from Him, while the Interior Man is represented here by Abram. Consequently 'the covenant between Me and you' means the union of the Internal Man, or Jehovah, with the Interior Man, and so with the Lord's Human Essence.
