What does Stein want? How did Elie respond to Stein's request for information? (chapter 3)

Eliezer and his father meet a distant relative, Stein of Antwerp, who wants news of his wife Reizel and his children. Eliezer's father does not recognize the man since he was generally more interested in community matters in his old life, and Eliezer lies to the man, telling him that his family is doing well. Stein weeps with joy at the news. He continues to visit them for the next few weeks and occasionally brings them extra bread. He is thin and dried up, but he says that he is kept alive by the thought that his family is still alive. When a transport arrives from Antwerp, however, he discovers the truth about his family, and Eliezer never sees Stein again.
