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 16:28-29
28
You have played the prostitute also with the Assyrians, because you were insatiable; yes, you have played the prostitute with them, and yet you weren't satisfied.
29
You have moreover multiplied your prostitution to the land of merchants, to Chaldea; and yet you weren't satisfied with this.
