But Potiphar refused to give credence to what he said, and he had also him stripped and beaten. The wife of Potiphar, standing by the door, saw how Joseph was abused, and she sent word to her husband, "Thy verdict is unjust, for thou punishest the free-born youth that was stolen away from his place as though he were the one that had committed a crime." As Joseph held firmly to what he had said, Potiphar ordered him to prison, until his masters should return. In her sinful longing for him, his wife wanted to have Joseph in her own house, and she remonstrated with her husband in these words: "Wherefore dost thou keep the captive, nobly-born slave a prisoner? Thou shouldst rather set him at liberty and have him serve thee." He answered, "The law of the Egyptians does not permit us to take what belongs to another before all titles are made clear," and Joseph stayed in prison for twenty-four days, until the return of the Ishmaelites to Egypt. Meanwhile they had heard somewhere that Joseph was the son of Jacob, and they therefore said to him: "Why didst thou pretend that thou wast a slave? See, we have information that thou art the son of a powerful man in Canaan, and thy father mourns for thee in sackcloth." Joseph was on the point of divulging his secret, but he kept a check upon himself for the sake of his brethren, and he repeated that he was a slave. Nevertheless the Ishmaelites decided to sell him, that he be not found in their hands, for they feared the revenge of Jacob, who, they knew, was in high favor with the Lord and with men. The shopkeeper begged the Ishmaelites to rescue him from the legal prosecution of Potiphar, and clear him of the suspicion of man theft. The Ishmaelites in turn had a conference with Joseph, and bade him testify before Potiphar that they had bought him for money. He did so, and then the chief of the eunuchs liberated him from prison, and dismissed all parties concerned. With the permission of her husband, Potiphar's wife sent a eunuch to the Ishmaelites, bidding him to buy Joseph, but he returned and reported that they demanded an exorbitant price for the slave. She dispatched a second eunuch, charging him to conclude the bargain, and though they asked one mina of gold, or even two, he was not to be sparing of money, he was to be sure to buy the slave and bring him to her. The eunuch gave the Ishmaelites eighty pieces of gold for Joseph, telling his mistress, however, that he had paid out a hundred pieces. Joseph noticed the deception, but he kept silent, that the eunuch might not be put to shame.[99]
