When this terrible judgment was about to be executed the Lord provided the following means of deliverance for his people: Each family in Israel were commanded at a given time to take a lamb without blemish, a male of the first year, for a Passover Offering, and it was to be killed in the evening. "And they shall take of the blood and strike it on the two side-posts, and on the upper doorpost of the houses, wherein they shall eat it. And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it. * * * And ye shall eat it in haste; it is the Lord's passover. For I will pass through the land of Egypt this night, and will smite all the first-born in the land of Egypt, both man and beast: and against all the gods of Egypt, I will execute judgment: I am the Lord. And the blood shall be to you for a token upon the houses where ye 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. And this day shall be unto you for a memorial; and ye shall keep it a feast to the Lord throughout your generations: ye shall keep it a feast by an ordinance forever."[A] [Footnote A: Exodus xii.] Thus was the Passover established. Of it the late President Taylor said: "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 doorpost; 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] [Footnote A: "Mediation and Atonement," p. 106.]
