Exodus 12:38-39

And a mixed multitude went up also with them; and flocks, and herds, {even} very much cattle. {a mixed...: Heb. a great mixture} And they baked unleavened cakes of the dough which they brought forth out of Egypt, for it was not leavened; because they were thrust out of Egypt, and could not tarry, neither had they prepared for themselves any victual.
