Exodus 12:40-42

International Standard Version

⁴⁰ Now the time that the Israelis lived in Egypt was 430 years. ⁴¹ At the end of 430 years, to the very day, all the tribal divisions of the Lord went out from the land of Egypt. ⁴² That was for the Lord a night of vigil^[a] to bring them out of the land of Egypt. This same night belongs to the Lord, and is to be a vigil for all the Israelis from generation to generation.
