Luke 10:38-40

Luke 10:38-40. Now it came to pass, as they went, that he entered into a certain village: and a certain woman named Martha received him into her house. And she had a sister called Mary which also sat at Jesus’ feet, and heard his word. But Martha was cumbered about much serving, and came to him and said, Lord, dost thou not care that my sister hath left me to serve alone? bid her therefore that she help me.

Agitated, distressed Martha was afraid that something would go wrong with the dinner. She had too much on her hands - too much on her brain. That led her to blame her sister Mary, and to try to get the Lord to blame her too. There is a strong tincture of self-righteousness in Martha’s speech.
