Among the minor Midrashim, esoteric attributes of Enoch are expanded upon. In the "Sefer Hekalot", Rabbi Ishmael is described as having visited the Seventh Heaven, where he met Enoch, who claims that earth had, in his time, been corrupted by the demons Shammazai, and Azazel, and so Enoch was taken to Heaven to prove that God was not cruel. Similar traditions are recorded in Sirach. Later elaborations of this interpretation treated Enoch as having been a pious ascetic, who, called to mix with others, preached repentance, and gathered (despite the small number of people on Earth) a vast collection of disciples, to the extent that he was proclaimed king. Under his wisdom, peace is said to have reigned on earth, to the extent that he is summoned to Heaven to rule over the "sons of God".
