1020. That these things are meant becomes clear from the fact that everything put together as history from Genesis 1 down to Eber in Chapter 11 means something different from what appears in the letter, and from the consideration that the historical narratives there are purely made-up history customary among the most ancient people. When attesting the truth of some matter they would say that 'Jehovah said it'. Here however 'God' is used because the subject is the spiritual Church. And they did the same when anything true was being, or had been, put into effect.

In Psalm 51:12; 54:4, "uphold me" signifies to support; here, the spiritual life of the humble. (Divine Love and Wisdom 49)

In Isaiah 41:10, it signifies the power and wisdom of the Lord to sustain man in temptations. (Apocalypse Explained 298[10])

In Isaiah 42:1, it signifies the Divine Human of the Lord. (Arcana Coelestia 2159[4])

In Ezekiel 30:6, the failure of people who "uphold Egypt" signifies that outward knowledges held in the memory are not sustaining, and people who trust in them will perish through evil loves. (The Inner Meaning of the Prophets and Psalms 153)
