Exodus 12:37-39

Revised Standard Version

³⁷ And the people of Israel journeyed from Ram′eses to Succoth, about six hundred thousand men on foot, besides women and children. ³⁸ A mixed multitude also went up with them, and very many cattle, both flocks and herds. ³⁹ And they baked unleavened cakes of the dough which they had brought 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 provisions.
