Joseph confirmed all she had said, and they embraced and kissed each other in token of their betrothal, which they celebrated by a banquet with Potiphar and his wife. The wedding took place later in the presence of Pharaoh, who set a golden crown upon the head of the bridegroom and the bride, gave them his blessing, and made a seven days' feast in their honor, to which he invited the magnates and princes of Egypt and of other countries. And during the seven days of the wedding festivities the people were prohibited, under penalty of death, from doing any manner of work; they all were to join in the celebration of Joseph's marriage.
