Ma'aser is a Hebrew term that refers to the practice of giving a tenth of one's income or produce to support religious and charitable causes. This practice is rooted in Jewish law and tradition, emphasizing the importance of sharing wealth and helping those in need. The concept of ma'aser is often associated with agricultural produce in ancient times, where farmers would set aside a portion of their harvest for the Levites and the poor. Today, many people apply this principle to their earnings, contributing to synagogues, charities, and community projects.
