Arcana Coelestia # 9679
9679. 'And you shall bring the ark of the Testimony in there, within the veil' means the coming-into-being of the inmost heaven within that uniting intermediary. This is clear from the meaning of 'the veil' as the intermediary uniting the two heavens, dealt with in 9670, 9671; and from the meaning of 'the ark of the Testimony' as the inmost heaven, dealt with in 9485; its coming-into-being is meant by 'bringing the ark in there'.
Arcana Coelestia # 1242
1242. 'Eber's two sons' means the two aspects of worship - internal and external - and these two sons were called Peleg and Joktan, 'Peleg' meaning the internal worship of that Church, and 'Joktan' the external worship of that Church. This is clear chiefly from the fact that 'Eber and the Hebrew nation' means in the internal sense this second Ancient Church, and also because every Church has an internal and an external, for without the internal it neither is nor can be called a Church, but idolatry. Since 'sons' has reference to aspects of the Church it is clear that one son means the internal aspect of the Church, the other the external. A similar duality frequently occurs elsewhere in the Word, for example, that meant previously by Lamech's wives, Adah and Zillah, 409, and that meant later on by Leah and Rachel, and by Jacob and Israel, and others like these. The descendants of Joktan are dealt with in this chapter, those of Peleg in the next.
