Exodus 12:5-9 "Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats: And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening. And they shall take of the blood, and strike it on the two side posts and on the upper door post 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. Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the purtenance thereof."
The word of the LORD that Moses and Aaron told to the children of Israel was specific. As part of their last meal in Egypt, they were to eat a lamb, but not just any lamb. The lamb was to be as near perfect as they could find among their flocks. This lamb would be a male without blemish and of the first year (a young lamb).
This lamb would be separated from the flock. He would be kept up from the tenth to the fourteenth day of the month. While there was a lamb for each household, they were told the lamb should be slain in the evening. The death of the lamb of each household would occur at the same time.
The blood of the lamb would be applied to the doorposts and lintel of the house where the lamb was being eaten. The lamb would be roasted in the fire. It would be eaten with unleavened bread and bitter herbs. It would not be eaten raw, nor would it be boiled, and it would be consumed in its entirety.
Beloved, remember the prophecy of Abraham when he told Isaac that God would provide Himself a lamb for a burnt offering (Genesis 22:8)? We see that message affirmed here in the passover lamb. Jesus was the Lamb of God, and He was without any blemish (sin). He was separate from (the firstborn among) His brethren (Romans 8:29), and He was offered amid great suffering (fire) for us. His blood is our covering and allows us to draw nigh unto God. He was killed in the evening (the ninth hour) for all His people. Even today, when we are made aware of our sinful nature by the Holy Ghost and allowed to see Jesus’ suffering for us, we eat that with bitter herbs (sorrow) and unleavened bread (simplicity). This, dear ones, is how we are delivered from the bondage of sin. To Him all the glory belongs!
