The claim that Judaism commemorates the Passover of the Old Testament is as nonsensical as the one that asserts that Judaism's "Noahide Laws" are based on Noah, the Biblical patriarch who is mocked and degraded in Orthodox Judaism. Like the ersatz Talmudic Noah, the bogus rite in Judaism misnamed "Passover" is derived from the Talmud - using the Bible as a prop. Here below is information on Judaism's foundational Passover text. Surprise, surprise, it's not the Old Testament but rather the Haggadah, a thoroughly Talmudic work. "Haggadah" means "telling." Its recitation kicks off the week-long festival of Passover. In the Diaspora, the Seder takes place on the first two nights of the festival, and the Haggadah serves as the manual. The Haggadah doesn't tell the story of Exodus so much as it depicts 5 rabbinical sages exegetically parsing it via Deuteronomy. Rabbis Eliezer, Yehoshua, Elazar ben Azariah, Akiva, and Tarphon spice up the biblical tale of the flight from Egypt by arguing over the minutiae of the Passover rites, which were originally compiled in the Talmud, the Jewish book of religious laws. This occurred very roughly, in circa 200 CE, but one thing remains certain: the Talmud, and the Haggadah along with it, was a response to a catastrophe so great it threatened to destroy a people. The Talmud was compiled as a result of the absolute destruction of Herod’s temple, in which every stone was carried away leaving no trace of it’s existence. In 66 CE, when the Roman general Vespasian swept into Jerusalem, Judaism was a cultic, oral religion, with Herod's massive temple as its lodestar. Everything happened in the temple complex. Four years later, Vespasian's son Titus razed it to the ground. "Where was God under the rubble?" wondered the Rabbis. "How to praise him now that the temple was gone?" The sages agreed: Jews would have to **become** a people of the book, or they would disappear. **Hence, they were NOT a people of the book before this time.**
