Arcana Coelestia # 4821
4821. 'And she conceived and bore a son' means that from this came the falsity of the Church. This is clear from the meaning of 'conceiving and bearing' as acknowledging in faith and action, dealt with in 3905, 3915, 3919, and from the meaning of 'a son' as the truth of the Church, but in the contrary sense falsity, dealt with in 489, 491, 533, 1147, 2623, 3373, 4257. Consequently 'she conceived and bore a son' here means that the Church among the tribe of Judah acknowledged falsity in faith and action. The reason this son means the falsity of the Church is that he was the firstborn, and in the Ancient Churches 'the firstborn' meant the truth of faith, 352, 3325, and so in the contrary sense falsity, which was also the meaning of the firstborn among men and the firstborn among beasts in Egypt, 3325. The fact that truth is not meant but falsity is evident from what follows shortly, for in verse 7 it says, 'Er, Judah's firstborn, was evil in the eyes of Jehovah, and Jehovah caused him to die'. Er, this son's name, also implies the particular nature of this falsity, even as Onan, his second son's name, implies the particular nature of that meant by him, namely what is wrong or evil.
Dwell
To “dwell” somewhere, then, is significant – it’s much more than just visiting – but is less permanent than living there. And indeed, to dwell somewhere in the Bible represents entering that spiritual state and engaging it, but not necessary permanently. A “dwelling,” meanwhile, represents the various loves that inspire the person who inhabits it, from the most evil – “those dwelling in the shadow of death” in Isaiah 9, for example – to the exalted state of the tabernacle itself, which was built as a dwelling-place for the Lord and represents heaven in all its details. Many people were nomadic in Biblical times, especially the times of the Old Testament, and lived in tents that could be struck, moved and raised quickly. Others, of course, lived in houses, generally made of stone and wood and quite permanent. In between the two were larger, more elaborate tent-style structures called tabernacles or dwellings; the tabernacle Moses built for the Ark of the Covenant is on this model.
