Arcana Coelestia # 3109
3109. Verses 23-25 And he said, Whose daughter are you? Tell me now, is there at your father's house a place for us to spend the night? And she said to him, I am the daughter of Bethuel, the son of Milkah, whom she bore to Nahor. And she said to him, There is both straw and also much fodder with us, and a place to spend the night.
'He said, Whose daughter are you?' means further investigation concerning innocence. 'Tell me now, is there at your father's house a place for us to spend the night?' means investigation concerning the good of charity. 'And she said to him, I am the daughter of Bethuel, the son of Milkah, whom she bore to Nahor' means here, as previously, the whole origin of it. 'And she said to him' means perception. 'There is both straw' means factual truths. 'And also much fodder with us' means the goods that go with these. 'And a place to spend the night' means that state.
Mother
In general, mothers in the Bible represent the Lord's church on earth. In some cases "mother" more specifically refers to the truth of the church, the true teachings the church has about the Lord and about life. This makes sense if you think about it. Mothers are the vehicles through which new people are created; the church (in a broad sense) is the vehicle through which new ideas about the Lord and new good actions are created. And just as a mother is filled with love -- for her children and husband -- so also is the church filled with love, both for its ideas and uses and also for the Lord.
