5213. 'Fat and good' means into which facts matters of faith and charity could be instilled. This is clear from the meaning of 'fat' when used in reference to known facts meant by 'heads of grain' (in that facts are able to receive the good of faith and can therefore have matters of faith instilled into them; for facts are vessels, and when 'fatness' is used in reference to them, the ability to receive such things as are matters of faith springing from charity is meant); and from the meaning of 'good' when used in reference to known facts meant by 'heads of grain' (in that facts are able to receive the good of charity and can therefore have matters of charity instilled into them). 'Fat' has regard to matters of faith and 'good' to matters of charity because these are their usual connotations throughout the Word. For whenever these two adjectives are applied to the same thing, one is connected with matters of faith, the other with matters of charity; and this is so on account of the marriage of truth and good present in every individual part of the Word, 683, 793, 801, 2173, 2516, 2712, 4137 (end), 5138. The fact that 'fat' means matters of faith and 'good' matters of charity is also evident from the previous parallel description regarding the cows, 5199, 5200.

[2] The facts which are able to have matters of faith and charity instilled into them are very many. They include all facts known to the Church which are meant in the good sense by 'Egypt', dealt with in 4749, 4844, 4964, 4965, consequently all facts which are truths about correspondences, representatives, meaningful signs, influx, order, intelligence and wisdom, affections. Indeed they include all truths, both visible and invisible ones, that are descriptive of the interior and the exterior aspects of the natural world, because such truths correspond to spiritual truths.

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'.
