The first-century Jewish historian, Josephus, who was also a Jewish priest, gives us an idea of what the Passover would have been like at the time of Jesus. According to Josephus' calculations there would have been around 2.7 million Jews celebrating the Passover in Jerusalem, and over 256,000 Passover lambs slain. The blood of the Passover lambs was poured over the altar in the Temple. The amount of blood is hard to fathom. As the author of Hebrews says, "without blood, there can be no forgiveness of sins." The Jewish Mishnah and the second-century church father, Justin Martyr, both report that the Passover lambs were then roasted on sticks, one vertical and the other horizontal, giving the appearance that the Passover lambs were "crucified" while roasted over the fire. All of these things help us better understand what Saint Paul wrote to the Corinthians: "Christ, our Passover Lamb, has been sacrificed."
