3709. 'In you will all the families of the ground be blessed' means that all truths taught by doctrine which look to good will be joined to good. This is clear from the meaning of 'being blessed' as being joined together, dealt with in 3504, 3514, 3530, 3565, 3584, from the meaning of 'families' as goods and also truths which look to good, dealt with in 1159, 1261, and from the meaning of 'the ground' as that which is the Church's, consequently the doctrine of good and truth within the natural or external man, which 'Jacob' represents here, dealt with in 268, 566, ago, 3671. From this it is evident that 'in you will all the families of the ground be blessed' means that all truths taught by doctrine which look to good will be joined to good. Truths taught by doctrine which look to good are matters of doctrine concerning love to the Lord and charity towards the neighbour, which are said to be joined to good within the natural man when satisfaction and delight exists in knowing those things with the intention of acting upon them.

3671. 'You and your seed with you' means to the good and the truth born from this good. This is clear from the representation of Jacob, to whom 'you' refers here, as the good of truth, or good that is a product of truth, dealt with above, and from the meaning of 'seed' as the good and truth of faith, dealt with in 1025, 1447, 1610, 2848, 3373. 'With you' means that it was allied to the good of truth, represented by 'Jacob'. Good and truth are like seeds and the soil. Interior good is like seed that is productive, though not unless it is sown in good soil. Exterior good and truth are like the soil in which it is made productive. The former, that is to say, the seed, which is interior good and truth, cannot otherwise take root. This is why a person's rational is regenerated first of all, for the rational is where the seeds are; then after that the natural is regenerated to serve as the soil for them, 3286, 3288, 3321, 3368, 3493, 3576, 3620, 3623. And because the natural is like the soil, good and truth can be made fruitful and be multiplied within the rational, which could not take place if the soil where the seed has its root were anywhere else. From this comparison one may see as in a mirror what regeneration is like and the numerous arcana that go with it.

[2] Understanding good and truth and willing them is the function of the rational, and perceptions of good and truth resulting from this are like seeds; but knowing them and doing them is the function of the natural. Facts and deeds are like the soil. When a person has an affection for the facts that corroborate what is good and true, the more so when he experiences joy in acting them out, those facts are seeds that are present and growing in the natural as their own proper soil; and there they grow. As a consequence good is made fruitful and truth is multiplied, and they are constantly springing up out of that soil into the rational and perfecting it. The situation is different when a person understands what is good and true, and also interiorly perceives that he wills something, and yet does not desire to know these things, let alone do them. In that case good cannot be made fruitful nor truth be multiplied within the rational.
