Arcana Coelestia#624
624. It is clear that a state which is not a state of the Church is the subject here from the fact that in this verse and those that follow in chapter the name God is used, whereas in previous verses it was Jehovah. When the Church does not exist the name God is used, but when it does exist, it is Jehovah; for example in Genesis 1, when the Church did not exist, He was called God, but in the next chapter when it did, He was called Jehovah God. 'Jehovah' is the holiest of names, and belongs to the Church alone. Not so 'God', for no nation was without gods. Consequently the same holiness was not attached to the name God. Nobody was allowed to utter the name Jehovah except him who had knowledge of the true faith; but anyone was allowed to utter the name God.
Arcana Coelestia#4103
4103. 'Jacob rose up' means a raising up of the good meant by 'Jacob'. This is clear from the meaning of 'rising up' as that which implies a raising up, dealt with in 2410, 2785, 2912, 2927, and from the representation of 'Jacob' as the good of the natural, often dealt with already, at this point good which is coming closer to the Divine because it is to be separated from intermediate good, or 'Laban', 4073. By the raising up that is meant by 'rising up' one should understand a coming closer to the Divine. As regards man, he is said to be raised up when he comes closer to heavenly things, and the reason for this is the belief that heaven exists raised up or on high. But this description of where heaven is is due to the appearance; for heaven and therefore the things that belong to heaven, namely celestial and spiritual ones, do not exist on high but in what is internal, see 450, 1735, 2148. Consequently a person is in heaven inwardly when spiritual love and faith are present in him.
