In Genesis 11:24, Terah, Abraham's father, as a nation represents idolatrous worship. (Arcana Coelestia 1353)

In Genesis 11:31, when Terah leaves Ur for Haran, partway to Canaan, it signifies that people who were in idolatrous worship were instructed in the celestial and spiritual things of faith, so that a representative church could arise from them. (Arcana Coelestia 1373)

In Joshua 24:2, it notes that Terah served other gods. In Arcana Coelestia 5628[2] there are interesting details about this. Abraham's ancestors worshipped 'God Shaddai', which name connotes temptations and, after hardship, comfort.

1373. Verse 31 And Terah took Abram his son, and Lot, the son of Haran, his son's son, and Sarai his daughter-in-law, the wife of Abram his son; and they set out together from Ur of the Chaldeans to go into the land of Canaan. And they came as far as Haran and remained there. These words mean that people whose worship was idolatrous received instruction in the celestial and spiritual things of faith in order that from them a representative Church might come into being.
