3101. 'So as to know whether Jehovah had prospered his way or not' means regarding Divine Truth, as to what sort it was. This is clear from the meaning of 'way' as truth, dealt with in 627, 2333. The Divine nature of that truth is meant by the words 'whether Jehovah had prospered' which amounts to the same as, whether it was from Jehovah, that is, from the Divine. Accordingly what sort of truth is meant, for the truths that are summoned from the natural man into the rational man are not all received, only those that accord with the good there, and on being sown and implanted in this way act as one with that good. The rest, even though they may have appeared as truths prior to being raised up, are nevertheless not received because they are not acknowledged. Good is that which acknowledges its own truth, and truth that which acknowledges its own good. That it was an acknowledgement of what sort of truth it was, and that thus this truth was received, is also evident from what follows next.

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'.
