In Jewish history, an unblemished lamb, the firstborn of its mother, was sacrificed in the Temple to represent or stand as a symbol of the Lamb of God who would eventually be sacrificed for our atonement. This was part of the Law of Moses that God gave to our ancient Israelite ancestors. It was designed to remind them that the Son of God would come and atone for their sins. Unfortunately, they lost sight of that over time. However, when Jesus came, he fulfilled the law of Moses and taught that the sacrifice he wanted from then on was a broken heart and a contrite spirit. This was actually what God wants (and wanted) from all His children, no matter what age of time they have lived. That innocent lamb represented an innocent Savior.
A lamb was either a young sheep or a young goat:
Exodus 12:5 Your lamb shall be without blemish, a male of the first year. You may take it from the sheep or from the goats.
A lamb was the primary offering in the Mosaic sacrificial system. It was offered on 8 or 9 occasions. For example, the continual burnt offering which was offered each morning and evening, also a lamb was offered on the first day of each month.
One special occasion was the Passover lamb. Israel was delivered from God's judgement on Egypt through the sacrifice of the Passover lamb.
Probably the Passover lamb was what John the Baptist had in mind when he called Jesus the Lamb of God.
John 1:29 The next day John saw Jesus coming toward him, and said, "Behold! The Lamb of God who takes away the sin of the world!
Most Ashkenazi Jews do not eat lamb during Passover. Sephardim will eat lamb during Passover to remember the offering of thanks that we gave when the Temple stood.
Lambs were the animal to be slaughtered because the Egyptians worshiped lambs as one of their gods. By slaughtering lambs, the Israelites were showing their rejection of idolatry.
The Passover Lamb
A lamb.
The Torah (Exodus ch.12) specifies matzoh, bitter hers and the meat of the pesach-sacrifice. Other foods are not mentioned, but wine, vegetables and fruits were probably on the menu.
Lamb can be kosher for Passover. However, Ashkenazi Jews traditionally do not eat lamb during Passover.
"Paschal" means "of or relating to the Passover," and is most often applied to the sacrifice of the "paschal lamb." (God's instructions to the children of Israel regarding the first Passover are found in Exodus 12). The paschal lamb was a "type" (foreshadowing) of the sacrifice of Christ.John 1:29 - The next day John saw Jesus coming toward him, and said, "Behold! The Lamb of God who takes away the sin of the world!" [NKJV]
In Exodus, 12:1–28 each Israelite family is commanded to sacrifice a lamb so that the final plague (the death of the firstborn) will pass over their houses, and the final verses cited above ask that this become an annual ritual in commemoration of the first Passover. So, for as long as the Temple in Jerusalem was in operation, Jews made Passover sacrifices, with each family bringing a lamb and then taking home a good part of the meat to eat at dinner after the sacrifice. This meal, where the sacrifice was eaten "with matzah (unleavened bread) and bitter herbs" is the origin of today's Passover Seder. Note that the Passover sacrifice was not a sin sacrifice. If anything, it was a thanksgiving sacrifice, made to thank God for the the salvation of the Israelites from Egyptian bondage.
The first night of Passover is the Seder night. During the Seder-meal, there are a number of symbolic foods on the table. One of them is a roasted lamb or goat shank-bone, chicken wing, or chicken neck; symbolizing the korban Pesach (Passover sacrifice), which was a lamb that was offered in the Temple in Jerusalem, then roasted and eaten as part of the meal on Seder night.
The Seder meal uses either a lamb bone or a turkey/chicken neck to represent the Paschal (lamb) sacrifice. The Israelites offered a lamb as a sacrifice at the first Passover. They put the blood of this lamb on their doorways as a signal for the Angel of Death to "Pass-Over" their houses and not kill their firstborn sons. All the other firstborn sons of Egypt died in the tenth and final plague. Modern Passover meals can use a chicken or turkey neck in place of the lamb bone since the Holy Temple is unavailable and they therefore want to use something dissimilar to the sacrificial lamb, yet still use a bone to remind them of the sacrifice.
John the Baptist calls Jesus the 'lamb of God'. - Joh 1:29. Here Jesus is being directly likened to the passover lamb. The passover lamb had to be perfect with out blemish. Jesus was born without sin, he lived a sinless life. The passover lamb had to die and it's blood was shed to save Israel's first born from death. In the same way it was necessary for Jesus to die as payment for sin. The lamb's blood had to be painted on the the door frames to show God the people were trusting Him for salvation. Salvation is the same today through faith in Jesus and His death as the payment for our sin.
