Joseph Habib examines the attitudes of medieval Karaite exegetes and Saadya Gaon with regard to the qere and ketiv in the Masoretic Hebrew Bible on the basis of their commentaries and Arabic translations. Habib presents clear evidence that both Saadya and various Karaite exegetes relied on qere as well as ketiv for their exegesis. He shows that the main motivation to use one of the other as the basis of interpretation is harmonization with parallel verses.
