The book includes numerous partial translations of Romance poems, described as "merely exegetic". And here is found a twofold series of exegetic expositions. Adjectives are exegetic or exegetical (e.g., exegetical commentaries). Only a few of Ben Zoma's exegetic teachings have been preserved. "brahmana" evidently have for their groundwork the same stock of traditional exegetic matter. The principal subject of Ben Zoma's exegetic research was the first chapter of Genesis. Massignon believes a number of people could have compiled this exegetic work. The "Bahir" assumes the form of an exegetic midrash on the first chapters of Genesis. The post-classical period is marked by the exegetic methodology of Ibn Kathir. By his comments on scripture, also, he largely stimulated Hebrew, grammatical, and exegetic studies.
