These collected prayers and instructions were printed for Marrano refugees, Jews from the Iberian Peninsula who had converted or been forced to convert to Christianity. Some of their descendents moved to Amsterdam where Jews could practice their faith openly. Included in this small bilingual Hebrew and Spanish edition are blessings for the entire year according to the Sephardic rite, a perpetual liturgical calendar, a Passover haggadah, prayers for the sick, and prayers for martyrs who were burned at the stake during the Inquisition. This page includes the formula for reciting the counting of the <em>omer</em>, a measure of barley offered in the ancient Temple in Jerusalem from the second day of Passover for forty-nine days until the Jewish holiday of Shavuot, the Feast of Weeks.
