Exodus 12:36-40

And the LORD gave the people favour in the sight of the Egyptians, so that they lent unto them such things as they required. And they spoiled the Egyptians.

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

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

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.

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