EXODUS 12:7,13 And they shall take some of the blood and put it on the two doorposts and on the lintel of the houses. And when I see the blood, I will pass over you; and the plague shall not be on you to destroy you when I strike the land of Egypt.The Egyptians had no protection from the destroyer, but the people of Israel who put the blood of a lamb on their dwellings were safe.The blood represented the Blood of the Lamb slain from the foundation of the world – Jesus Christ (Revelation 13:8)..The blood applied stopped the destroyer. With blood on the door of the Israelites in Egypt, no evil dared enter their dwelling. Christ is our Passover Lamb. Likewise, we are kept safe through the protection of the divine Blood of Jesus. 1 CORINTHIANS 5:7 For indeed Christ, our Passover, was sacrificed for us.
