Exodus 12:40-42

Revised Geneva Translation

⁴⁰ So, the dwelling of the children of Israel, while they dwelled in Egypt, was four hundred and thirty years.

⁴¹ And when the four hundred and thirty years had expired—on that very same day— all the hosts of the LORD departed out of the land of Egypt.

⁴² It is a night to be kept holy to the LORD, because He brought them out of the land of Egypt. This is the night of the LORD which all the children of Israel must keep throughout their generations.
