So he bought him for twenty pieces of silver; thus each of the brothers obtained two drachmæ, and therewith they bought shoes.[410] To this the prophet Amos refers in two places (ii. 6; viii. 6), and in the Testament of the Twelve Patriarchs, which is received as canonical by the Armenian Church, Zebulun relates the same circumstance, that the brethren supplied themselves with sandals from the money which they got by the sale of Joseph. Joseph went along with the Ishmaelites till they passed his mother’s tomb; then his grief overcame him, and he burst forth into bitter tears and cried, “O mother, mother! I am an outcast and a slave, I the child of the wife Jacob loved. When thou wast dying, thou didst show me to my father, and bade him look on me, and be comforted for my loss. O mother, mother! hast thou no thought of thy son? Awake and see the miserable condition of thy child; shake off thy sleep; be my defence against my brethren, and comfort my father. Awake and stand up to judge my quarrel, awake and plead my cause with God! awake and look upon the desolation of the soul of my father who cherished thee, and who for fourteen years served a hard bondage for his beloved Rachel! Console him, I pray thee, and, by the voice that he loves, soothe the grief of his last days.” It was moonlight, and the caravan was resting. A low voice issued from the tomb. “My son! my son Joseph! my child! I have heard the voice of thy crying. I know all thou hast suffered, my son, and my grief is as deep as the sea. But put thy trust in God, who is the help of thy countenance and thy God! Rise, my child, and have patience. If thou knewest the future, thou wouldst be comforted.”[411] One of the chiefs of the caravan, wearied with the cries of Joseph, came to drive him from the tomb, but suddenly a dark and threatening cloud appeared in the sky over his head, and he desisted in fear. In the Testament of the Twelve Patriarchs, Benjamin says that a man struck Joseph as he lagged on the way, whereupon a lion fell upon the man and slew him. The sun was about to set, when the caravan entered Heliopolis, the chief city of Egypt, which was then under the government of Rajjan, an Amalekite. Joseph’s face shone brighter than the mid-day sun; and as this new light from the east shone in the city, and cast the shadows towards the declining sun, all the women and damsels ran out upon the terraces or to the windows to see. Next day he was placed for sale before the palace of the king. All the wealthy ladies of Heliopolis sent their husbands or relations to bid for the beautiful youth, but he was purchased by Potiphar, the king’s treasurer,[412] who was childless, and designed making Joseph his adopted son and heir.
