5533. 'They and their father' means by the truths and the good of truth in the natural. This is clear from the representation of the sons of Jacob, to whom 'they' refers here, as the truths in the natural, dealt with in 5403, 5419, 5427, 5458, 5512; and from the representation of Jacob, to whom 'their father' refers here, as the good of truth which is also in the natural, dealt with in 3659, 3669, 3677, 3775, 4234, 4273, 4538. An explanation of what a discernment by truths and the good of truth in the natural is can indeed be given; but when that explanation passes into the understanding the matter will seem to be extremely obscure. Yet it will be seen in so to speak the clear light of day by spirits when it passes into their understanding. Such matters are for them some of the less hard to understand. This also makes clear to some extent the nature of the difference between a person's intelligence while he is in the world and the inferior light shining here and when he is in heaven and the superior light shining there.

3775. 'Jacob said to them' means the truth of good. This is clear from the representation of 'Jacob' as the Lord's Divine Natural; dealt with already. Since every single thing, wherever it may be, has reference to good and truth, 3166, 3513, 3519, so also does everything in the natural; and since during a person's regeneration good and truth in the natural exist in a different state at the beginning from the state in which they exist during the process of regeneration and at the end of it, 'Jacob' therefore represents truth and good present in the natural, in a relationship to each other determined by the particular state; here he represents the truth of good. But to explain their varying relationship to each other every time they occur would cast the subject into obscurity, especially with people who have no distinct concept of truth and good, let alone of truth through which good comes, and of truth which stems from good.
