With Day One, Genesis 1.1–5, as a focus and informed by the understanding that all texts are intertexts, S. D. Giere shapes and employs a method that harnesses the idea of intertextuality for the purpose of exploring the history of interpretation of a biblical text. With a unique compilation of intertexts of Gen 1.1-5, the work explores the intertexual reach of Day One in Hebrew and Greek texts up to c. 200 CE. What emerges is a glimpse of the intertextuality of Day One that provides insight into the complexity of the intertextuality of a biblical text and the relationship of intertextuality and interpretation.
