The hardest chapter to write for my book on the Jewishness of Jesus was the one on resurrection. I tried to avoid it, but my editor insisted. Resurrection of the dead is not a topic we discuss much in synagogues.
In fact, many Jews and Christians today believe Jews have never believed in the resurrection of the dead. Yet, the Talmud says faith in resurrection is one of the three core ideas of Judaism. Look at chapter 37 of the Book of Ezekiel.
In it the Prophet Ezekiel envisions a valley full of dry bones. He speaks to the bones. He tells them God will breathe life into them. They will have skin and flesh and become a great army.
The bones symbolize the people of Israel, who will rise again and return to their land. The text is not purely a symbolic vision of rebirth. It is physical, with the spirit giving life to the bones of the dead. The text is traditionally read during the week of Passover.
