Exodus 12:40–42

40 The time that the Israelites lived in EgyptA was 430 years.k 41 At the end of 430 years, on that same day, all the Lord’s military divisions went out from the land of Egypt. 42 It was a night of vigil in honor of the Lord, because he would bring them out of the land of Egypt. This same night is in honor of the Lord, a night vigil for all the Israelites throughout their generations.l
