With such words, Joseph endeavored to cure the wife of his master of the wanton passion she had conceived for him, while he took heed to keep far from a heinous sin, not from fear of the punishment that would follow, nor out of consideration for the opinion of men, but because he desired to sanctify the Name of God, blessed be He, before the whole world. It was this feeling of his that Zuleika could not comprehend, and when, finally, carried away by passion, she told him in unmistakable language what she desired, and he recoiled from her, she said to Joseph: "Why dost thou refuse to fulfil my wish?
Am I not a married woman? None will find out what thou hast done." Joseph replied: "If the unmarried women of the heathen are prohibited unto us, how much more their married women? As the Lord liveth, I will not commit the crime thou biddest me do."
In this Joseph followed the example of many pious men, who utter an oath at the moment when they are in danger of succumbing to temptation, and seek thus to gather moral courage to control their evil instincts."
