In anticipation of the holiday of Shavuot—the Jewish festival that celebrates the receiving of the Ten Commandments and the Torah at Sinai—our students learned from a sofer (a scribe) about some of the many rules and procedures regarding the writing of sacred texts. Zerach Greenfield, a sofer STaM from New York, demonstrated the tools a scribe uses. The acronym STaM stands for Sefer Torah, teffilin, and mezuzot.
