What is the deeper meaning behind the name change of Sarai to Sarah? What is the concept of the 'Woman of Valor' who is the 'crown of her husband?' In what way was Sarah greater than Avraham? What is meant when the letter 'yud' of the name Sarai splits and half is distributed to Avraham and half to Sarah? Why does the 'yud' fly in front of the Throne of Hashem's glory and complain?

Why was Sarah originally a 'princess for herself,' and subsequently a 'princess for the world?' Find out in this week's Parsha Podcast.
