Input: Consider Input: Question: When was the first person to describe the Nash Papyrus text born? Passage:The Nash Papyrus is a collection of four papyrus fragments acquired in Egypt in 1898, inscribed with a Hebrew text which mainly contains the Ten Commandments and the first part of the Shema Yisrael prayer, in a form that differs substantially from the later, canonical Masoretic text and is in parts more similar to the chronologically closer Septuagint. It has been suggested that the text might have been the daily worship of a Jew living in Egypt at the time. The fragments comprise a single sheet and are not part of a scroll. The papyrus is of unknown provenance, although it is allegedly from Fayyum. The text was first described by Stanley A. Cook in 1903. Though dated by Cook to the 2nd century CE, subsequent reappraisals have pushed the date of the fragments back to about 150–100 BCE. The papyrus was by far the oldest Hebrew manuscript fragment known at that time, before the discovery of the Dead Sea Scrolls in 1947.
