What does the Siftei Kohen (Shach) suggest regarding the use of Ma'aser money?

The Siftei Kohen, also known as the Shach, addresses the usage of Ma'aser money, which refers to the tithe set aside from one's income. The suggestion that it can be used for mitzvot one can’t afford is rooted in the understanding that Ma'aser money is intended to support not only charity but also the performance of mitzvot. This includes expenses related to fulfilling commandments that an individual may find financially challenging.

When donations from this money are allocated to support mitzvot—such as purchasing a lulav and etrog for Sukkot, funding a local synagogue, or assisting in a religious education—one is essentially using Ma'aser to enhance their ability to engage in religious obligations. This is highly valued as it allows individuals to fulfill spiritual duties without the burden of financial strain.

The other options are more restrictive. Limiting the usage solely to educational purposes or to support charities narrows the broader application intended for this fund. Similarly, stating it can only be used for rebuilding homes would overlook the diverse ways in which this money can enhance religious life and observance. Therefore, the flexibility and broader applicability of Ma'aser money to support mitzvot makes this option the most aligned with the Shach
