Exodus 12:37-39

21st Century King James Version

³⁷ And the children of Israel journeyed from Rameses to Succoth, about six hundred thousand on foot who were men, besides children.

³⁸ And a mixed multitude went up also with them, and flocks and herds, even very much cattle.

³⁹ 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.
