Exodus 12:40-42

Living Bible

^40-41 The sons of Jacob and their descendants had lived in Egypt 430 years, and it was on the last day of the 430th year that all of Jehovah’s people left the land. ⁴² This night was selected by the Lord to bring his people out from the land of Egypt; so the same night was selected as the date of the annual celebration of God’s deliverance.
