Older Asch leaves the US, rather than testify in front of the House of Unamerican Activities Committee. He also denounces God of Vengeance, echoing what was said against it in the Peretz salon, toward the beginning of the play. He sees it as the work of a younger man, and no longer appropriate in the current time and place (1952, in that scene in the play). As he leaves, he faces upstage and sees Lemml, or a vision of Lemml. And then, the rain begins, and the rain scene is performed one more time, in Yiddish. I think the scene happens for a number of reasons. As the character of Eugene O'Neill says earlier, the rain scene presents a pure vision of love and sensuality in an amoral world. It's a reminder of hope and joy, against so much pain and loss. The characters of Older Asch and Lemml are both as jubilant watching the scene as the two women are performing it. Also, the scene is performed in Yiddish, without subtitles. At that point, Vogel hopes we've heard it enough times in English that we can understand it in its original language, as if we were all native Yiddish speakers. It's a Kaddish for a once vibrant language and people.
