Charles Spurgeon Commentary John 11:28

Because she knew that the Jews hated the Saviour, she could not tell what would come of it if they knew of his coming, so she whispers to her:

And when she had so said, she went her way, and called Mary her sister secretly, saying, The Master is come, and calleth for thee.

Martha's title for Christ could be rendered, "The Teacher, The authoritative Teacher," yet I am glad our translators put it "The Master."
