The relative age of these works can be determined by comparing the legend of Abraham as contained in the Apocalypse with those in the Talmud and in the Book of Jubilees. The legend of the raven in Jubilees (11:18) and the account of the conversion of Abraham in his boyhood are still unknown to the Apocalypse, while the legend of the fire of the Chaldees is found there still in its incipient stage. The mockery of the idol "Barisat" is more extended in the Midrash than in the Apocalypse; also the condemnation of Terah as an idolater, as related in the Apocalypse, discloses the older aggadah (Genesis Rabba 39:7), whereas the Book of Jubilees presents the later one (compare Genesis Rabba 30:4 and 39:7, where Terah is treated quite mildly). The Book of Jubilees treats the Temple as still existing, and therefore can be dated prior to 70 AD, when the Temple was destroyed.
