Exodus 12:13-14 says this: 13) And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt. 14) And this day shall be unto you for a memorial: and ye shall keep it a feast to the LORD throughout your generations: ye shall keep it a feast by an ordinance forever. The most important feast on the Jewish calendar, Passover, was orchestrated by the LORD to carry out judgement on all sin (not just Egypt) but made a provision for His chose people to be spared, but more importantly, He orchestrated a mass prophetic event in which a sinless, spotless lamb was chosen for its blood as a token of their obedience. Exodus 12:5 says this: Your Lamb shall be without blemish, a male of the first year; ye shall take it out from the sheep, or from the goat. The fact is: the LORD chose this event to show His people what He would eventually do to spare everyone who obeyed from the curse of death and bring them out of bondage. During this important feast, God instructs His people in Exodus 12:19: Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land. 1 Corinthians 5:7-8 reveals the spiritual significance behind this command and reveals the true meaning of Passover: Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our Passover is sacrificed for us: therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. The leaven (or the yeast) in the bread represents sin, and the prophetic act of cleansing your house of any trace of yeast was God’s way of showing His people how He needed them to be: without sin. And for that to happen there needed to be the shedding of blood. The Last Supper took place on the first day of Passover, and this is not by coincidence. Jesus wanted to let His disciples in on one of His biggest revelations! Matthew 26:26-28 says, And as they were eating Jesus took bread, and blessed it, and brake it, and gave it to the disciples, and said, “Take, eat; this is my body.” And he took the cup, and gave thanks, and gave it to them, saying, “Drink ye all of it, for this is my blood of the new testament, which is shed for many for the remission of sins.” Without His disciples knowing the full significance of what Jesus was saying, Jesus was telling them (and all of us) that He would become the Passover sacrifice for us all. Jesus—our sinless, spotless Lamb—is the fulfillment of Passover so that anyone who applies the blood over our doorposts would be spared from the judgement of God. And we now have Jesus, our Lamb without blemish, to thank for all of eternity for offering Himself as our Passover on a tree on a mountain called Calvary.
