3386. 'And he said, She is my sister' means rational truth. This is clear from the meaning of 'a sister' as rational truth, dealt with in 1495, 2508, 2524, 2556. By rational truth is meant, as stated just above, that which is seen as the truth, in whatever form people grasp it mentally or see it rationally. Isaac's saying that Rebekah was his sister, as Abraham on a previous occasion in Egypt had said that Sarah was his sister, Genesis 12:11-13, 19, and after that in Gerar, Genesis 20:2, 5, 12, embodies a similar arcanum, as may be seen from the explanation given at those two points. And because a like event took place on three occasions, and also these are recorded in the Word, it is clear that it holds an arcanum of supreme importance within it which cannot possibly be known to anyone except from the internal sense. What this arcanum is however is evident from what follows.

2523. 'She is my sister' means that it was the rational which ought to be consulted, that is to say, He thought that such a consultation should take place. This is clear from the meaning of 'a sister' in this chapter as rational truth, dealt with in 1495, 2508. In the internal sense of the Word the Lord's entire life is described, as it was going to be when He was in the world, even as to His perceptions and thoughts. For these things had been foreseen and provided, since they were from the Divine. A further reason for this provision of them in the internal sense was so that the things of the Lord's life in the world might be manifested as present realities to the angels, who perceive the Word according to its internal sense. In this way the Lord was placed before them, and at the same time the manner in which He gradually cast off the human and put on the Divine. Unless these things had been manifested to the angels as present realities by means of the Word, and also by means of all the religious observances of the Jewish Church, it would have been necessary for the Lord to come into the world immediately after the fall of the Most Ancient Church, which is called 'Man' or Adam; for the Lord's Advent was foretold immediately the Fall took place, Genesis 3:15. And what is more, the human race existing at that time could not otherwise have been saved.

[2] As regards the Lord's life itself, it was a life in which the Human was constantly advancing towards the Divine, even to complete union, as stated many times already. For to fight the hells and overcome them He had to do so from the Human, since no conflict with the hells takes place from the Divine. That being so, He was pleased to put on the human as any other person; to be a small child as any other; to grow in knowledge and cognitions which were represented and meant by Abraham's sojourning in Egypt, Chapter 12, and now in Gerar. Thus He was pleased to develop the rational like any other person and to dispel the shadow enveloping it and to bring it into light, and to do so from His own power. That the Lord advanced in this manner from the Human to the Divine, no one can be in any doubt if he merely considers the fact that He was a small child, and learned to talk as any small child does, and so on. But there was this difference, that the Divine itself dwelt within Him because He had been conceived from Jehovah.
