Exodus 12:40

³⁸And a great mixed company went up with them, and sheep and oxen and very much cattle.

³⁹And they baked the dough which they brought out of Egypt, unleavened cakes, for it had not been leavened; for the Egyptians cast them out, and they could not remain, neither did they prepare provision for themselves for the journey.

— Exodus 12:40 —

⁴¹And it came to pass after the four hundred and thirty years, all the forces of the Lord came forth out of the land of Egypt by night.

⁴²It is a watch kept to the Lord, so that he should bring them out of the land of Egypt; that very night is a watch kept to the Lord, so that it should be to all the children of Israel to their generations.
