Apocalypse Explained #664
664. Verse 11. And after the three days and a half, signifies when it is finished, thus the end of the old church and the beginning of the New Church. This is evident from the signification of "the three days and a half," as being fullness and completion as to the end of the old church, when there is the beginning of the New Church (See above, n. 658). It is said "after the three days and a half" because in the Word "days" signify states, here the last state of the church; for in the Word all times, as "hours," "days," "weeks," "months," "years," "ages," signify states, as here the last state of the church, when there is no longer any good of love or truth of faith left. Because "days" signify states, and the establishment of the Most Ancient Church is treated of in the first chapter of Genesis, and it becomes established successively from one state to another, it is there said:
That there was evening and there was morning the first day, the second, the third, the fourth, the fifth, and the sixth days, even to the seventh, when it was finished (Genesis 1:5, 8, 13, 19, 23, 31; 2:2);
and the "days" there do not mean days, but the successive states of the regeneration of men at that time, and the consequent establishment of the church with them. So also elsewhere in the Word.
Arcana Coelestia #6651
6651. 'And a new king arose over Egypt' means separated factual knowledge, which is opposed to the Church's truths. This is clear from the representation of Pharaoh, to whom 'king' refers here, as factual knowledge in general, dealt with in 6015. The word 'king' is used because in the genuine sense 'king' means truth, 1672, 2015, 2069, 3670, 4581, 4966, 5044, 6148, and in the contrary sense falsity; and since 'king' refers here to Pharaoh, false factual knowledge is meant, that is, factual knowledge that is opposed to the Church's truths. This also explains why the expression 'new king' is used, for the one who lived in Joseph's time represented factual knowledge that accorded with the Church's truths. For the meaning of 'Egypt' as factual knowledge, here that knowledge in particular, see above in 6638.
