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.
Arcana Coelestia #3643
3643. I have noticed that those in heaven dwell beneath a clear, bright sky like that of morning and midday, extending also towards evening, and likewise in a warmth like that of spring, summer, and autumn. But those in hell dwell under a dim, cloudy, and darkened sky, and also in the cold [of winter]. I have noticed that between the two in general a balance is kept; also that insofar as love, charity, and consequently faith are present in angels, they dwell under a clear sky and in the warmth of spring, and that insofar as hatred and consequently falsity are present in those in hell they dwell in thick darkness and in coldness. And as stated above, the light in the next life holds intelligence within it, the warmth love within it, while thick darkness holds insanity within it, and cold hatred within it.
