Jewish biblical scholar Jon Levenson notices the discrepancies between Exodus and Deuteronomy, specifically regarding the length of time for eating unleavened bread (Exodus 12:18; Deuteronomy 16:8). The Rabbis noticed them too. Instead of concluding that this is a signal of multiple sources, he follows the rabbis in suggesting that (in Matthew Levering’s summary) “the operative law is to be discovered by taking both passages into account. The unity of the Mosaic Torah requires that all data be considered.”

That’s an important lesson, for Christian interpreters no less than rabbinic ones.
