According to the Book of Exodus, manna (an edible substance that God provided to sustain the Israelites as they wandered through the wilderness) was delicious: “Its flavor was like wafers made of honey.” (Exodus 16:34) Yum!

After a full day of costume changes, ritual immersions, lotteries, sacrifices, blood sprinklings, confessions, mysterious moments in the Holy of Holies, and much more, the high priest’s day comes to an end. The mishnah on yesterday’s daf tells us that the high priest would mark the end of Yom Kippur with a feast for his […]

The Jewish month of Tevet always begins during Hanukkah. But when the first of that month also happens to be Shabbat, it’s a busy day in synagogue.  As Rabbi Titzhak Nappaha says on today’s daf: When the new moon of Tevet occurs on Shabbat, we take out three Torahs: From one, we read the topic of the […]

Juneteenth is an American holiday celebrating the end of slavery. This prayer reflects on the core story of the Jewish people — the Exodus from Egypt — which impels us to fight slavery everywhere.
