Whether shall we praise more, Mary's humility, or her docility? I do not see her take a stool and sit by him, or a chair and sit above him; but as desiring to show her heart was as low as her knees, she sits at his feet. She was lowly set, and richly warmed with his heavenly beams." - Spurgeon's Sermon Notes
