“Seven days were completed, after the Lord had struck the Nile” (Exodus 7:25). “Seven days were completed, after the Lord had struck the Nile” – Rabbi Yehuda and Rabbi Neḥemya: One says: For twenty-four days he would forewarn them before the plague began, and for seven days the plague would affect them. And one says: For seven days he would forewarn them, and for twenty-four days the plague would affect them. According to the one who says that for twenty-four days he would forewarn them, “seven days were completed” for the plague. According to the one who says that for seven days he would forewarn them, “seven days were completed after the Lord had struck,” during which he would forewarn them regarding another plague.
