For Christ, our paschal lamb, has been sacrificed (1 Corinthians 5:7) 

The feast of the Passover was so named because the angel of death which the Lord sent, passed over the house of the Israelites but killed the first born in every Egyptian home. This feast was also referred to the feast of the unleavened bread, because the people left Egypt in such a hurry that they did not have time to add yeast to the bread they were baking (Exodus 23:15). 

The smeared blood on the door posts of the Israelites was a sign to the angel of death – not to strike. 

Jesus and His disciples were in Jerusalem and they were instructed by Jesus to make ready the Passover meal (Matthew 26:19). The Passover meal involved the eating of a lamb that was roasted and its blood was sprinkled by the priest on the base of the altar in the temple. This symbolized the blood sprinkled on the door posts, to save the first-born among the Israelites from death. 

Little did the disciples realize that within a few hours the crucified Jesus, would become the roasted lamb that was lying on their table and whose blood would become an everlasting atonement for sin. 

Jesus was crucified outside the city of Jerusalem because the city was packed with pilgrims.
