3399. The expression 'lying with a wife' means in the internal sense perverting and adulterating truth, here truth that is Divine, because 'a wife' - Rebekah - represents Divine Truth, as shown above. This may be seen from the consideration that instances of lying together, adultery, and prostitution in the Word do not mean anything other than perversions of good and falsifications of truth, as shown in 2466, 2729. The reason why they do so is that all adultery is absolutely contrary to conjugial love, so much so that it is destructive of it; and conjugial love originates in the marriage of good and truth, 2508, 2618, 2727-2759, 3132. Consequently things that are contrary to good and truth, or that destroy them, are in the Word called forms of adultery.

[2] But it should be realized that those who belong to the spiritual Church are not able to adulterate good to such an extent that they profane it, for the reason that they are not able to receive good so far as to perceive it, as those who are celestial do. They are able however to profane truth because they are able to acknowledge it. Yet in the final period of the Church they are not able even to acknowledge truth, because at that time universal disbelief prevails concerning the Lord, concerning life after death, and concerning the internal man. And the disbelief which reigns universally makes it impossible for them to penetrate into the interior truths of faith. That which prevails with everyone universally limits them and keeps them back from entering more deeply into such things, even when the person is unaware of that universal disbelief and also when he supposes that he does believe.

[3] But those who are able to profane good are such as belong to the celestial Church, for they are able to receive it so as to perceive it, as was done by those living before the Flood who have consequently been segregated from everyone else and are kept in a hell separated from the hells of others - regarding which see 1265-1272. The prevention of the occurrence ever again of the profanation of good is meant by the reference to Jehovah expelling man and causing cherubim to dwell away from the east towards the garden of Eden, and the flame of a sword turning this way and that to guard the way of the tree of life, Genesis 3:24. On these matters, see 308, 310.

2508. 'She is my sister' means rational truth. This is clear from the meaning of 'a sister' as rational intellectual truth, dealt with in 1495. That rational truth is meant by 'a sister' cannot be seen by anyone except from the heavenly marriage; for the things that descend from that marriage have links with one another - resembling the ties of blood-relationships and relationships by marriage on earth, concerning which see 685, 917 - and in ways endlessly varying. The heavenly marriage exists solely between Divine Good and Divine Truth. Conceived from that marriage there exist with man the capacities to understand, to be rational, and to have knowledge; for without this conception from the heavenly marriage no one can possibly be endowed with understanding, reason, or knowledge, and cannot consequently be a human being. Insofar therefore as he draws from the heavenly marriage he is human. The heavenly marriage exists within the Lord Himself, so that the Lord is that marriage itself; for He is Divine Good itself and at the same time Divine Truth. The heavenly marriage exists with angels and men insofar as love to the Lord and charity towards the neighbour, and consequently insofar as faith derived from these exist with them, that is, insofar as the Lord's good and the truth derived from this do so. When this is the case with them they are called 'daughters and sons', and in relation to one another 'sisters and brothers', but with differences. The reason rational truth is called 'a sister' is that it is conceived from the influx of Divine Good into the affection for rational truths. The good conceived in this way in the rational is called 'a brother', and the truth 'a sister'. But this will be clearer from the words spoken by Abraham in verse 12 of this chapter, 'And also she is truly my sister, my father's daughter but not my mother's daughter; and she became my wife'.
