Arcana Coelestia #1187
1187. 'He built Nineveh, and Rehoboth city, and Calah' means that in this way they formulated for themselves doctrinal teachings concerning faith. This is clear from the meaning of 'Nineveh and Rehoboth and Calah', to be dealt with in the paragraphs following immediately after this, and from the meaning of 'a city' in the Word, as doctrine, true or heretical, as shown already in 402.
Ezekiel 23:2-3
2
Son of man, there were two women, the daughters of one mother:
3
and they played the prostitute in Egypt; they played the prostitute in their youth; there were their breasts pressed, and there was handled the bosom of their virginity.
