Rabbi Zilber worked tirelessly to help Russian women receive gittin (bills of divorce) after being abandoned by their husbands. Many of them were "complicated by the fact that the partners of the broken marriage were often living in different countries, and locating them was far from easy". However locating them was often necessary to comply with Jewish law. Often this was meant endless efforts, exquisite inventiveness, and (as he puts it in his autobiography) "a large dose of Divine providence". At the end of his autobiography he shares a sample from his "impressing collection of unusual stories" that came out of this endeavor.
