'Haran,' as mentioned in Genesis 12:5, signifies an obscure state.

In Genesis 11:28, this signifies inward idolatrous worship.

In Genesis 28:10, this signifies external good and truth.

In Genesis 29:4, this signifies collateral good of a common stock.

(Referencat: Arcana Coelestia 1367, Genesis 11)

1367. That 'Haran' means interior idolatrous worship and 'Terah' idolatrous worship in general has been stated and shown already. That 'the land of his birth' means the source from which their idolatrous worship derived is clear from the meaning of 'birth' as a source and derivation, dealt with above at verses 10 and 27.
