In Genesis 11:28, Ur signifies a state of external worship in which there are falsities. (Arcana Coelestia 1368)

Ur signifies profane idolatry. (Arcana Coelestia 1373)

In Genesis 15:7, Ur signifies the first state of the Lord's external, or the maternal which he received by birth. It was from this that He was brought out. (Arcana Coelestia 1816)

(Odkazy: Arcana Coelestia 1365)

1816. 'Who brought you forth out of Ur of the Chaldeans' means the first state of the external Man. This becomes clear from the meaning of 'Ur of the Chaldeans'. The maternal part of the Lord which He received by birth, that is, what had been inherited from the mother, is what is meant here by 'Ur of the Chaldeans'. The nature of this has been described already. It was out of this maternal part, or what had been inherited from the mother, that He was 'brought forth' every time He overcame evils and falsities, that is, the hells.
