[6] The wandering student Channon arrives in the town of Brinitz, where he intensively studies the Kabbalah and fasts every day except Shabbat in an attempt to gain such purity that his prayers will be heard.
Rabbi Azrael sends Mikoel to the graveyard to notify Nissen's spirit that he is being summoned to the supreme rabbinical court in nearby Miropol.
At the trial, Nissen's spirit reminds Sender that in their youth they were great friends and they married their wives on the same day, after which they agreed that if they had children then these children would wed. Nissen's spirit continues that Channon sought Leah's hand but was rejected by Sender, who sought a better life for his daughter with a wealthier suitor.
Rabbi Azrael rules that the agreement is not binding because it applies to objects which did not exist yet when the agreement was made, but explains that the idea was put in Channon's mind that Leah was his destined bride and that Sender's actions have caused Nissen and Channon to be unable to find peace in the afterlife with no one to say Kaddish for them so he rules that Sender must give half of his possessions to the poor and every year light a candle and say Kaddish for the two deceased men as if they were his own family.
You could tell the play was written to instill these values for a Jewish audience, that without respect and obedience to elders only leads to tragedy.
