Notice in verse 3 that on the tenth day each person was to take a lamb for himself. In verse 5 we see that the lamb was to be without blemish, a male of the first year.
Think of Jesus when you look at these instructions. It could be either from the sheep or the goats. Jesus is a type of both sheep and goat. Remember in the atonement offering that one of the two goats typified Jesus. He was represented as a goat in that ceremony.
We are told that the lamb was to be kept until the 14th day of the same month and that it was then to have been killed at twilight. This was done by slitting its throat. They were then to take some of the blood and smear it on the doorposts and lintel of the houses where they would be eating the Passover.
So we see that the innocent lamb actually bled to death. This was how it died. Scripture says that the bones were not to be broken. It was to be roasted whole. Remember that Jesus' bones were not broken either.
We see in all these things that Jesus was the perfect antitype of this lamb that was slain at the Passover service. The blood was put on the lintel and on the doorpost as a sign for the death angel to pass over that house. And he was not to kill the firstborn who were inside. By means of the blood that was smeared on the lintel and the doorposts they were saved from the tenth plague—the plague of the death of the firstborn. It was the blood of the lamb that redeemed them. It bought back the firstborn of Israel. Otherwise, they would have been killed.
Jesus' ghastly death—the terrible scourging He endured—did the same thing for us. It bought us back. It redeemed us. The Protestants say He died of a broken heart. That is not true. Like the Passover lamb, He bled to death. His blood spilled onto the earth and He expired as an innocent and pure Man. He had never sinned—just like that lamb without blemish and without spot.
