Dedicated to my beloved Parents, z”l.

“Thou graciously endowest mankind with knowledge, and teachest understanding to humans. who graciously bestowest knowledge.”

“Sifra: Chapter 1. Rabbi Yishmael (rule 13) says: when two texts contradict each other, we follow the second, until a third text is found which reconciles them.”

Quoted from: Book of Prayers.  Ed. and trans. David de Sola Pool.  2nd ed.  New York: Union of Sephardic Congregations, 1986.
