Passover (Hebrew) is an annual Jewish remembrance of the Exodus, in which the people of Israel were freed from slavery in Egypt. Passover begins on the 15th day of the month of Nisan in the Jewish calendar, which is in spring in the Northern Hemisphere, and is celebrated for seven or eight days. It is one of the most widely observed Jewish holidays.
"Passover represents the passing from one season into another season (esoterically, the passing from the seven serpents of fire into the seven serpents of light, which can be raised only by the Lamb-Christ) and a preparation for the journey into winter, in which Saturn will come with his scythe in order to perform his duty, which is death; in winter everything dies, in order for Hades to take over. [...] According to Judaism, they have to kill a male goat without any blemish – pure – to kill it in certain ways in order to celebrate the Passover. When you read this Passover history in the Bible, you read how Moses performs great miracles, wonders, in front of the Pharaoh. And, indeed, he performs only ten, related with the Tree of Life." - from the lecture "Capricorn"
