Reading the words, "And it came to pass, that, when Abram came into Egypt," in , a Midrash asked why the text at that point mentioned Abraham but not Sarai. The Midrash taught that Abram had put Sarai in a box and locked her in. The Midrash told that when Abram came to the Egyptian customs house, the customs officer demanded that Abram pay the custom duty on the box and its contents, and Abram agreed to pay. The customs officer proposed that Abram must have been carrying garments in the box, and Abram agreed to pay the duty for garments. The customs officer then proposed that Abram must have been carrying silks in the box, and Abram agreed to pay the duty for silks. The customs officer then proposed that Abram must have been carrying precious stones in the box, and Abram agreed to pay the duty for precious stones. But then the customs officer insisted that Abram open the box so that the customs officers could see what it contained. As soon as Abram opened the box, Sarai's beauty illuminated the land of Egypt.
