7039. 'Behold, I kill your son, your firstborn' means the annihilation of faith devoid of charity, and the consequent devastation of truth among them. This is clear from the meaning of 'killing' as annihilation; and from the meaning of 'firstborn son', that is to say, of Pharaoh and the Egyptians, as faith devoid of charity, dealt with in 3325. For 'Pharaoh' and 'the Egyptians' have represented the facts known to the Church, 4749, 4964, 4966, 6004, thus known facts which form part of faith since these facts are ones that the Church possesses. But because they turned that factual knowledge into magic, 6692, and their deeds were as a consequence evil and devoid of any charity, the mere knowledge of matters of faith, thus faith without charity, is meant by 'their firstborn sons'. That the mere knowledge of them is meant by 'the firstborn of Egypt' is evident from the meaning of 'the firstborn of Israel' as the faith that is wedded to charity, dealt with above in 7075.

[2] The expression 'faith devoid of charity' is used, but faith in this case is used to mean the mere knowledge of matters of faith, because faith cannot exist where there is no charity. With those who are not governed by charity matters of faith are merely items stored in the memory; and in the memory they take the same form as any other factual knowledge. Nor does any real knowledge of the truth that composes faith reside there, because it has been debased by false ideas and also serves as the means to bolster up falsities. Since this is what faith devoid of charity is like, it is annihilated among the wicked in the next life, with whom truth suffers complete devastation. This is allowed to happen to prevent them from using truths as the means to attain evil objectives, and so to prevent hell from dominating in any way among them over such things as belong to heaven, and to guard against their being left hanging as a consequence between heaven and hell. Such annihilation and such devastation of truth is what is meant by the firstborn in Egypt being killed. The destruction after that of the Egyptians in the Sea Suph represented a subsequent state of damnation or spiritual death of such people; for once they have been deprived of matters of faith or truth, which were like wings lifting them up, they immediately drop like weights into hell.

4964. 'Was made to go down to Egypt' means to factual knowledge which the Church possessed. This is clear from the meaning of 'Egypt' as knowledge, or factual knowledge in general, dealt with in 1164, 1165, 1186, 1462. But no explanation of the essential nature of that factual knowledge properly meant by 'Egypt' has been provided as yet. In the Ancient Church there was doctrinal knowledge and there was factual knowledge. Doctrinal knowledge had regard to love to God and charity towards the neighbour, whereas factual knowledge had to do with the correspondences of the natural world with the spiritual world, and with the representations of spiritual and heavenly realities within natural and earthly ones. Such was the factual knowledge of those in the Ancient Church.

[2] Egypt was one of those parts of the world and one of those kingdoms where the Ancient Church also existed, 1138, 1385; but since in that land mainly factual knowledge was handed down from one generation to another, 'Egypt' means factual knowledge in general. This also explains why frequent reference is made to Egypt in the prophetical part of the Word, where that knowledge is meant specifically by 'Egypt'. What is more, the actual magic practised by the Egyptians had its origin in the same knowledge; for they were acquainted with the correspondences of the natural world with the spiritual, and at a later time, after the Church among them had come to an end, they misused these in magical practices. Now because such factual knowledge existed among them - that is to say, knowledge which taught correspondences, and also representatives and meaningful signs - and because this factual knowledge was the servant of the doctrinal teachings of the Church, especially in their understanding of things stated in their Word (for the Word of the Ancient Church was both prophetical and historical, like the Word that exists today, though this is a different Word, see 2686) 'he was made to go down to Egypt' consequently means made to go down to the factual knowledge which the Church possessed.

[3] Because the Lord is represented by 'Joseph' and the words 'Joseph was made to go down to Egypt' are used here, the meaning is that when the Lord was to glorify His Internal Man, that is, make it Divine, He first of all assimilated the factual knowledge possessed by the Church. Then, starting from and using that knowledge He advanced towards things increasingly interior and at length even to those that were Divine. For it pleased Him to glorify or make Himself Divine in conformity with the same kind of order as that by which He regenerates the human being or makes him spiritual, 3138, 3212, 3296, 3490, 4402. That is to say, there is a gradual advance from external ideas, which are known facts and the truths of faith, towards internal ones, which are ideas of charity towards the neighbour and of love to Him. From this one may see what is meant by the following words in Hosea,

When Israel was a boy I loved him, and out of Egypt I called My son. Hosea 11:1.

These words refer to the Lord, see Matthew 2:15.
