Exodus 12:40-42

New Century Version

⁴⁰ The people of Israel had lived in Egypt for four hundred thirty years; ⁴¹ on the very day the four hundred thirty years ended, the Lord’s divisions of people left Egypt. ⁴² That night the Lord kept watch to bring them out of Egypt, and so on this same night the Israelites are to keep watch to honor the Lord from now on.
