St Luke 10:39-42

And she had a sister called Mary, who sitting also at the Lord's feet, heard his word. But Martha was busy about much serving. Who stood and said: Lord, hast thou no care that my sister hath left me alone to serve? speak to her therefore, that she help me. And the Lord answering, said to her: Martha, Martha, thou art careful, and art troubled about many things: But one thing is necessary. Mary hath chosen the best part, which shall not be taken away from her.
