Compare 2 Enoch 26:3 and Apocalypse of Abraham 21:4

"... The evidence of Leviathan’s unique status, in comparison with God’s other creatures, receives its most paradoxical expression in his role as the cosmological foundation of the entire universe. Apocalypse of Abraham 21:4 unambiguously identifies him as the axis mundi by placing the whole universe on top of the monster ... One of the instances in which an antagonistic entity appears to be envisioned as a cosmological foundation can be found in 2 Enoch, a Jewish apocalypse written, according to present scholarly consensus, in the first century CE, in the time very close to the composition of the Apocalypse of Abraham, which is usually dated by scholars to the second century CE ... in 2 Enoch one may detect the presence of two foundations - one upper “positive” foundation represented by the luminous aeon Adail, and another lower, negative, “dark” foundation, represented by Arukhas. There is a certain symmetry between the upper and lower foundations. This development is important for our study. We will encounter a similar parallelism between cosmological foundations in our study of later Jewish materials, especially in the Book of Zohar, where the role of Leviathan as a negative cosmological foundation of the universe is juxtaposed with Rabbi Simeon’s role as the positive cosmological “pillar” of the world ..."
