There's a brief story in Luke 10:38-42, where Jesus is visiting in the home of Mary, Martha, and Lazarus - two sisters and their brother. It's a busy time at their house, because people have come to see Jesus, and to marvel at Lazarus, who was just raised from the dead by Jesus. Martha is working to serve the guests, and Mary is sitting and listening. Martha asks Jesus to tell Mary to help her, and - surprisingly - he doesn't. Instead, he gently reproves Martha for worrying, and says that Mary has "chosen that good part, which shall not be taken away from her".

It doesn't seem fair, on the face of it. But here's what's going on in the internal sense of the story:

In verses 38-39, when the Lord stops in this village to visit Martha and Mary, it means that the Lord is received by people who are love truth and of good.

In verses 41-42, when Martha is busy and stressed, she represents our state of mind when we are in the affection of truth, but are not yet purified from the anxieties of self-love. Then the Lord instructs us, that we should pay attention to the higher affection of good, and exalt it in our lives.

In Genesis 4:22 and 12:13, this signifies intellectual truth. (Arcana Coelestia 1475)

In Genesis 24:30 and 24:59, this signifies the affection of truth. (Arcana Coelestia 3133, 3182)

In Genesis 24:60, this signifies a desire for truth. (Arcana Coelestia 3186)

In Genesis 30:8, this signifies temptation resulting in victory. (Arcana Coelestia 3927)

In Exodus 2:4, this signifies rational truth. (Arcana Coelestia 6727)

The Lord calls people who are in truth from the good of charity from Him 'sisters' in Matthew 12:50. 'Sister' denotes intellectual truth and 'wife' celestial truth.
