How truly chastity and purity reigned among Israel was shown by the division of the people into groups and tribes. Among all these thousands was found only a single man who was not of pure descent, and who therefore at the pitching of the standards could attach himself to none of the groups. This man was the son of Shelomith, a Danite woman, and the Egyptian, whom Moses, when a youth of eighteen, had slain for having offered violence to Shelomith, the incident that had necessitated Moses' flight from Egypt.
It had happened as follows: When Moses came to Goshen to visit his parents, he witnessed how an Egyptian struck an Israelite, and the latter, knowing that Moses was in high favor at Pharaoh's court, sought his assistance, appealing to him with these words: "O, my lord, this Egyptian by night forced his way into my house, bound me with chains, and in my presence offered violence to my wife. Now he wants to kill me besides."
Indignant at this infamous action of the Egyptian, Moses slew him, so that the tormented Israelite might go home. The latter, on reaching his house, informed his wife that he intended getting a divorce from her, as it was not proper for a member of the house of Jacob to live together with a woman that had been defiled. When the wife told her brothers of her husband's intentions, they wanted to kill their brother-in-law, who eluded them only by timely flight.
