The Lord performed two more miraculous signs that were plagues in the land of Egypt; a plague of locust that ate the remaining crops and then darkness over the land for three days. Just as before the Lord hardened Pharaoh's heart and he did not let the people go.
One more miraculous sign, the Passover and Pharaoh under compulsion would let the people go. Both the Passover feast and the feast of unleavened bread were instituted by this sign. Both of these are a type and picture of Jesus Christ and His church.
On the 10th day of the month a perfect lamb (could be a sheep or a goat) was selected out of the herd for each household. The lamb was to live with them for four days. Jesus walked amongst us for approximately 33 years, most of us would consider that to be a young man. At twilight on the evening of the 14th day (the Sabbath begins at twilight) the lamb was sacrificed and its blood was spread on the lintel and door post. Jesus was sacrificed for our sins, His blood must be on your heart and mind. The Lord past over all who had the blood of the lamb on the lintel and door post, the Lord will pass over all who have the blood of Jesus on their heart and mind. They ate the lamb quickly, devouring it, with nothing left over. Christ is to be totally consumed, He is not consumed in part, you cannot be a partial Christian.
The feast of unleavened bread was instituted to remember how the Israelites departed quickly from Egypt. They did not have time to allow the dough to rise. The Christian is to depart from this world and make haste to the door which is faith in Jesus Christ the Lord.
