The Book of Jubilees, Chapter Eleven (11). In this chapter, we discover the root cause for the meteoric rise of war, bloodshed, eating of blood, and idolatry among the sons of Noah. Disembodied spirits from the Giants lead men astray into worshipping idols, images, and familiar things. We learn about Abram (Abraham), and his devotion to the All Mighty God. This chapter produces a beautiful typology of spiritual warfare when Abram at 14 years of age chases Ravens away from his food source, ravens which were sent as agents of Satan (Mastema). We learn about the New Testament links to this ancient book regarding spiritual warfare and how Satan steals the seed or Word of God from humans, bringing them to destruction.
