"And the children of Israel went away, and did as the Lord had commanded Moses and Aaron, so did they. And it came to pass, that at midnight the Lord smote all the first-born in the land of Egypt, from the first-born of Pharaoh that sat on his throne, unto the first-born of the captive that was in the dungeon; and all the first-born of cattle. And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt: for there was not a house where there was not one dead. And he called for Moses and Aaron by night, and said, Rise up, and get you forth from among my people, both ye and the children of Israel: and go, serve the Lord, as ye have said. Also take your flocks and your herds, as ye have said, and be gone: and bless me also. And the Egyptians were urgent upon the people, that they might send them out of the land in haste; for they said, We be all dead men."--Ex., xii, 28-33. It is further said: "And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand the Lord brought us out from Egypt, from the house of bondage; and it came to pass, when Pharaoh would hardly let us go, that the Lord slew all the first-born in the land of Egypt, both the first-born of man, and the first-born of beasts; therefore I sacrifice to the Lord all that openeth the matrix, being males; but all the first-born of my children I redeem."--Ex., xiii, 14, 15. From the above quotations, amongst other important matters, it appears, that when the destroying angel passed by the houses of the children of Israel he found the blood of a lamb sprinkled on the door post; which was a type of the blood of Christ, the Lamb of God. The angel who was the executor of justice could not touch those who were protected by that sacred symbol; because that prefigured the sacrifice of the Son of God, which was provided at the beginning of creation for the redemption of the human family, and which was strictly in accordance with provisions then made by the Almighty for that purpose--"the Lamb slain from before the foundation of the world"--and accepted in full as an atonement for the transgressions of mankind, according to the requirements of eternal justice and agreed to by the Savior and His Father. A proposition is made to meet the requirements of justice, which proposal is accepted by the contracting parties, all these contracting parties being satisfied with the arrangement thus made. Hence it is said by one of the prophets: "Then he is gracious unto him, and saith, Deliver him from going down to the pit: I have found a ransom."--Job, xxxiii, 24. And further: "Therefore the redeemed of the Lord shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away."--Isaiah, li, 11.
