Exodus 12:39-41

American Standard Version

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 victuals. ⁴⁰ Now the time that the children of Israel dwelt in Egypt was four hundred and thirty years. ⁴¹ And it came to pass at the end of four hundred and thirty years, even the selfsame day it came to pass, that all the hosts of Jehovah went out from the land of Egypt.
