Go to the scene where Nefereteri(sp?) visits the home of Jochabed to try to convince her to leave. Jochabed holds up a piece of Levite cloth and says, "But we're Levites. We're the shepherds of our people." (or something like that). The Levites were not made the priests and "shepherds" of the Hebrews until Mount Sinai, after Moses returned with the 10 Commandments.
