Exodus 12:38-40

King James Version

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.

⁴⁰ Now the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years.
