Editing Menachem Mendel Futerfas (section)

=== For Tomchei Temimim and Pidyon Shvuyim ===
After his wedding, he stayed briefly with his mother in Kharkov, and then traveled with his wife to the city of Yegurovsk (a city approximately 100 kilometers from Moscow). Although he temporarily withdrew from his yeshiva activities for family matters, the administrators of the nationwide network of underground Tomchei Temimim yeshivas throughout Russia already recognized his talents and dedication, seeing him as most suitable for working to save the yeshivas. From a financial perspective - supporting the families of prisoners who risked their lives for Torah and mitzvos, maintaining the underground yeshivas, funding the constant relocations of the yeshivas, as well as significant amounts paid as bribes - placed a heavy financial burden on the organizers, and he was chosen to be one of those tasked with obtaining the necessary funding.

He accepted the position and entered the business world for this purpose. While he earned substantial profits, he and his family subsisted on bread and water, giving the vast majority of the profits to Tomchei Temimim. Additionally, whenever Anash activists needed large sums of money for pidyon shvuyim (redeeming captives), they would turn to Reb Mendel, and even when he didn't have the requested amount, he would borrow the money and transfer it to them.
