A stream of major commentators have given periods such as 210 or 215 years for the length of time in Egypt. Sources such as Demetrius the Chronographer and the Seder Olam hold this view.
I am looking for other significant sources (commentators, Rabbis, etc.) that hold this view and also meet the following criteria:
- Either predate the translation of the Septuagint or the first century C.E.
- Used primarily the Hebrew text rather than the Greek.
