Genesis 7:2, “Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.” The ceremonially clean animals would be needed as sacrifices after the Flood.
“Clean meat is defined as the meat of every animal that has the hoof cloven in two, and chews the cud. Some examples of clean meat are the ox (cattle), buffalo, sheep, goat, deer, gazelle, antelope and mountain sheep, just to name a few. Unclean meat examples are the pig, the camel, the hare and the rock badger.

From Genesis through Revelation, the Lamb is an idiom for the Messiah. Other animals are the crimson worm, goat and lion, that is, The Lion of Judah.
Genesis 22:8, “And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together.” Prophetic of Jesus as our propitiation.
Passover lamb, Exodus 12:5, “Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats”
Exodus 12:13, “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.” As the Israeli were protected by the blood of the lamb, we are protected by the blood of Jesus.
John 1:29, “The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.” Again, Jesus was to be our propitiation.
1 Peter 1:1, “But with the precious blood of Christ, as of a lamb without blemish and without spot:”
Revelation 22:3, “And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him” one of several verses in Revelation referring to the Lamb.
On the Day of Atonement/ Yom Kippur two goats were brought before the door of the tabernacle and cast lots, one as a burnt offering for the Lord and the other served as a scapegoat. The word translated "scapegoat" is Azazel, meaning "goat of departure."
Leviticus 16:10, “But the goat, on which the lot fell to be the scapegoat, shall be presented alive before the LORD, to make an atonement with him, and to let him go for a scapegoat into the wilderness.”
“The two goats symbolized two different aspects of atonement: "that which meets the character and holiness of God, and that which meets the need of the sinner as to the removal of his sins." Aaron's laying his hands on the head of the live goat pictures the placing of the sins of Israel (and of ourselves) on Christ, to be taken away forever.”
[Believer’s Bible Commentary]
Job 25:6, “How much less man, that is a worm? and the son of man, which is a worm?”
Psalm 22:6, “But I am a worm, and no man; a reproach of men, and despised of the people.” Jesus on the cross indicative of the crimson or scarlet worm who gave her life for her offspring leaving behind a crimson stain.
Genesis 49:9-10, “9 Judah is a lion's whelp: from the prey, my son, thou art gone up: he stooped down, he couched as a lion, and as an old lion; who shall rouse him up? 10 The sceptre shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh come; and unto him shall the gathering of the people be.” Shiloh, the Messiah.
Revelation 5:5, “And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Judah, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.” By His shed blood Jesus, the Lamb of God now the Lion of Judah, was qualify to break the seven seals.
Jesus came first as the servant Messiah, the Lamb of God; we are justified by His gift of Grace as the Goel/ Kinsman-Redeemer. At His second coming Jesus will return as the Lion of Judah, the avenger of blood.
THE CRIMSON OR SCARLET WORM
“The Crimson worm then lays her eggs under her body and the protective shell. When the baby worms (or larvae) hatch, they stay under the shell. Not only does the mother’s body give protection for her babies, but it also provides them with food – the babies feed on the LIVING body of the mother!
After just a few days, when the young worms grow to the point that they are able to take care of themselves, the mother dies. As the mother Crimson worm dies, she oozes a crimson or scarlet red dye which not only stains the wood she is attached to, but also her young children. They are colored scarlet red for the rest of their lives.”
