The book was arranged by its last editor in five sections, as in the Psalms and other Jewish Books.
Section I (1-36) is mainly concerned with pronouncing God’s judgment by Enoch on the angels, or watchers who fell through their love for the daughters of men (Gen. 6:1-4), and Enoch’s intercession for them. A weird description of Hades is found in this portion of 1 Enoch.
Section II (37-71) has three “parables,” or apocalyptic revelations, together with the story of Enoch’s translation into heaven.
Section III (72-87) is primarily concerned with furnishing a treatise on astronomy, the secrets of the movement of the stars as revealed to Enoch, who sees with his own eyes their very course, even the portals through which they enter and issue forth, for the purpose of transmitting the information to future generations.
Section IV runs along lines laid down in the first two portions dealing with the problem of sin and suffering of Israel. Enoch relates to Methuselah his visions of the deluge, the fall of the angels, and their punishment in the underworld, the deliverance of Noah, the Exodus, the giving of the Law, the conquest of Canaan, the time of the judges, the establishment of the united kingdom, the building of the temple, the story of the two kingdoms, the fall of the Northern Kingdom, and the Exile. This is followed by four periods of angelic rule up to the time of the Maccabean Revolt, the last assault of the Gentiles, and the great Judgment. The last part of Section IV contains the prediction of the foundation of the new Jerusalem, the conversion of the Gentiles, the resurrection of the righteous, and the coming of the Messiah.
Section V is without any account of the origin of sin but seems to be mainly devoted to the problem of suffering of the righteous and the prosperity of the oppressing sinners. It denounces evil and utters woes on sinners and promises blessings to the righteous. Within Section V is an older work “The Apocalypse of Weeks” (93:1-10; 91:12-19). It concludes (105): “In those days the Lord bade to summon and testify to the children of the earth concerning their wisdom: show (it) unto them; for ye are their guides, and a recompense over the world. For I and My Son will be united with them forever in the paths of uprightness and in their lives; and ye shall have peace; rejoice, ye children of uprightness. Amen.”
