3388. 'For she was good-looking' means that it could be received without difficulty because of its being called Divine. This is clear from the meaning of 'good-looking' as something which because of its form is pleasing and so is received without difficulty. The subject is those who possess matters of doctrine concerning faith but who do not have from good any perception of truth, only a conscience regarding what is true which consists simply of what their parents and teachers have told them. These are they who are called 'the men of the place (which is Gerar)', 3385, 3387. With these people the first stage in the confirmation of such truth is reached, in that it is called Divine, for now they immediately have a concept of that which is holy, and this contributes an overall confirmation to every single thing they are told even though they do not grasp it. Nevertheless what they are told must come within their ability to grasp those things. It is not enough for a person to know that something exists; he also wishes to know something about it, and the nature of it if any confirmation of it is to reach the understanding part of his mind, and come back from there. If that wish is not present something may indeed be introduced into the memory, but it remains there as no more than something dead, like a meaningless sound, and unless some confirmatory evidence from whatever source drives it home it slips away like the remembrance of something that merely made a sound.

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.
