The Precious Blood and the Mighty Hand
It is the night of the passover. The Jews are shut up in their houses, for God has warned that death is coming to Egypt this night! The blood of an unblemished lamb has been sprinkled on the transom and two side door posts of every home, according to the Lord's command. "The blood shall be to you for a sign upon the houses where you 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" (Exodus 12:13).
