(Hebrew חנוך Chanowk) An important symbolic figure in the book of Genesis. The son of Cain.
"And Enoch walked with the Elohim: and he [was] not; for the Elohim took him." - Genesis 5
"It is written, "and Enoch walked with the Elohim" (Genesis 5:24) and also, "train (heb. Chanoch) up a child in the way he should go" (Proverbs 22:6), meaning that certain child that is the angel Metatron. This is the meaning of the verse. Enoch became a child, Metatron; "with the Elohim", refers to Malchut and not with Yud Hei Vav Hei which is Zeir Anpin, because he became a servant of Malchut. "And he was not" (Genesis 5:24) means that he was not under the name Enoch, "for the Elohim took him" to be called in his name, for he became an angel of Elohim." - The Zohar
From The Legends of the Jews by Louis Ginzberg :
The sinfulness of men was the reason why Enoch was translated to heaven. Thus Enoch himself told Rabbi Ishmael. When the generation of the deluge transgressed, and spoke to God, saying, "Depart from us, for we do not desire to know Thy ways," Enoch was carried to heaven, to serve there as a witness that God was not a cruel God in spite of the destruction decreed upon all living beings on earth.
When Enoch, under the guidance of the angel 'Anpiel, was carried from earth to heaven, the holy beings, the ofanim, the seraphim, the cherubim, all those who move the throne of God, and the ministering spirits whose substance is of consuming fire, they all, at a distance of six hundred and fifty million and three hundred parasangs, noticed the presence of a human being, and they exclaimed: "Whence the odor of one born of woman? How comes he into the highest heaven of the fire-coruscating angels?" But God replied: "O My servants and hosts, ye, My cherubim, ofanim, and seraphim, let this not be an offense unto you, for all the children of men denied Me and My mighty dominion, and they paid homage to the idols, so that I transferred the Shekinah from earth to heaven. But this man Enoch is the elect of men. He has more faith, justice, and righteousness than all the rest, and he is the only reward I have derived from the terrestrial world."
Before Enoch could be admitted to service near the Divine throne, the gates of wisdom were opened unto him, and the gates of understanding, and of discernment, of life, peace, and the Shekinah, of strength and power, of might, loveliness, and grace, of humility and fear of sin. Equipped by God with extraordinary wisdom, sagacity, judgment, knowledge, learning, compassionateness, love, kindness, grace, humility, strength, power, might, splendor, beauty, shapeliness, and all other excellent qualities, beyond the endowment of any of the celestial beings, Enoch received, besides, many thousand blessings from God, and his height and his breadth became equal to the height and the breadth of the world, and thirty-six wings were attached to his body, to the right and to the left, each as large as the world, and three hundred and sixty-five thousand eyes were bestowed upon him, each brilliant as the sun. A magnificent throne was erected for him beside the gates of the seventh celestial palace, and a herald proclaimed throughout the heavens concerning him, who was henceforth to be called Metatron in the celestial regions: "I have appointed My servant Metatron as prince and chief over all the princes in My realm, with the exception only of the eight august and exalted princes that bear My name. Whatever angel has a request to prefer to Me, shall appear before Metatron, and what he will command at My bidding, ye must observe and do, for the prince of wisdom and the prince of understanding are at his service, and they will reveal unto him the sciences of the celestials and the terrestrials, the knowledge of the present order of the world and the knowledge of the future order of the world. Furthermore, I have made him the guardian of the treasures of the palaces in the heaven 'Arabot, and of the treasures of life that are in the highest heaven."
Out of the love He bore Enoch, God arrayed him in a magnificent garment, to which every kind of luminary in existence was attached, and a crown gleaming with forty-nine jewels, the splendor of which pierced to all parts of the seven heavens and to the four corners of the earth. In the presence of the heavenly family, He set this crown upon the head of Enoch, and called him "the little Lord." It bears also the letters by means of which heaven and earth were created, and seas and rivers, mountains and valleys, planets and constellations, lightning and thunder, snow and hail, storm and whirlwind--these and also all things needed in the world, and the mysteries of creation. Even the princes of the heavens, when they see Metatron, tremble before him, and prostrate themselves; his magnificence and majesty, the splendor and beauty radiating from him overwhelm them, even the wicked Samael, the greatest of them, even Gabriel the angel of the fire, Bardiel the angel of the hail, Ruhiel the angel of the wind, Barkiel the angel of the lightning, Za'miel the angel of the hurricane, Zakkiel the angel of the storm, Sui'el the angel of the earthquake, Za'fiel the angel of the showers, Ra'miel the angel of the thunder, Ra'shiel the angel of the whirlwind, Shalgiel the angel of the snow, Matriel the angel of the rain, Shamshiel the angel of the day, Leliel the angel of the night, Galgliel the angel of the solar system, Ofaniel the angel of the wheel of the moon, Kokabiel the angel of the stars, and Rahtiel the angel of the constellations.
When Enoch was transformed into Metatron, his body was turned into celestial fire--his flesh became flame, his veins fire, his bones glimmering coals, the light of his eyes heavenly brightness, his eyeballs torches of fire, his hair a flaring blaze, all his limbs and organs burning sparks, and his frame a consuming fire. To right of him sparkled flames of fire, to left of him burnt torches of fire, and on all sides he was engirdled by storm and whirlwind, hurricane and thundering.
