The fifth trial was when Sarah his wife was taken to Pharaoh to be (his) wife. And is there any man, who seeing his wife taken away to another man, would not rend his garments? But (he trusted in the Holy One, blessed be He,) that he would not approach her. Whence do we know that Sarah was taken to Pharaoh to be his wife? Because it is said, "And the princes of Pharaoh saw her" (Gen. 12:15).
Rabbi Joshua, son of Ḳorchah, said: In that night when our mother Sarah was taken, it was Passover night, and the Holy One, blessed be He, brought upon Pharaoh and upon his house great plagues, to make known that thus in the future would He smite the people of his land, as it is said, "And the Lord plagued Pharaoh and his house with great plagues" (Gen. 12:17). Concerning the Egyptians it is written, "Yet one plague more will I bring upon Pharaoh, and upon Egypt" (Ex. 11:1). Was this a plague? Was it not (the slaying of) the first-born of the Egyptians? But the slaying is compared with the plagues, therefore it is said, "And the Lord plagued || Pharaoh" (Gen. 12:17).
