Israel's redemption in future days will happen on the fifteenth of Nisan, the night of Israel's redemption from Egypt, for thus did Moses say, "In this night God protected Israel against the Angels of Destruction, and in this night He will also redeem the generations of the future."
Though the actual deliverance from Egypt took place in that night, the Hebrews did not leave the land until the following day.
During the same night God requited the Egyptians for their evil deeds in the sight of all the people, the night being as bright as day at the time of the summer solstice. Not one could escape the general chastisement, for by Divine dispensation none was absent from home at the time, so that none could fail to see the chastisement.
