In this Support Team Study, Passover Letters from the Elephantine Papyri, Nehemia Gordon concludes his conversation with Prof. Bezalel Porten, by delving into a series of Jewish letters written in southern Egypt in the 5th century BCE. They discover that the earliest reference to Passover outside the Bible is an Aramaic letter dealing with the same problem we face today: when to do Passover! They also look at evidence of Gentiles in ancient Egypt who kept the Sabbath in fulfillment of Isaiah's prophecy. Be sure to first watch The Aramaic Name of God and The Ancient Jewish Temple in Elephantine.
