We really need to look at the Passover celebration as revealed in the instructions given to Moses and Aaron in Exodus chapter 12 because the symbolism is wonderfully woven into the Jewish and the Christian experience.
Each household needed a lamb, a perfect male, and they had to take it on the tenth day of the month and not sacrifice it until the fourteenth day. Compare: Jesus entered Jerusalem on the 10th day and was crucified on the 14th day.
Passover restrictions required that they had to eat the lamb and not break any of the bones. Compare: Jesus was crucified, but His legs were not broken (as was the custom in crucifixions).
In celebrating the Seder (Passover) dinner Jews still put three pieces of unleavened bread together (representing the Father, Son, and Holy Spirit) then take the middle piece, break it and wrap it in white cloth (symbolizing Christ’s death) and hide it (the burial). If you’ve seen Matzah bread you know it is striped and pierced (as was Jesus – whipped and later pierced with a sword). Later the bread is found (resurrection). The third cup of wine is drunk; it is the cup of redemption.
