The Book of Jasher 71
1And when Moses was eighteen years old, he desired to see his father and mother and he went to them to Goshen, and when Moses had come near Goshen, he came to the place where the children of Israel were engaged in work, and he observed their burdens, and he saw an Egyptian smiting one of his Hebrew brethren.
2And when the man who was beaten saw Moses he ran to him for help, for the man Moses was greatly respected in the house of Pharaoh, and he said to him, My lord attend to me, this Egyptian came to my house in the night, bound me, and came to my wife in my presence, and now he seeks to take my life away.
4And the Hebrew went to his house, and Moses returned to his home, and went forth and came back to the king's house.
5And when the man had returned home, he thought of repudiating his wife, for it was not right in the house of Jacob, for any man to come to his wife after she had been defiled.
6And the woman went and told her brothers, and the woman's brothers sought to slay him, and he fled to his house and escaped.
7And on the second day Moses went forth to his brethren, and saw, and behold two men were quarreling, and he said to the wicked one, Why dost thou smite thy neighbor?
10And the angel of the Lord took the sword from the hand of the captain of the guard, and took his head off with it, for the likeness of the captain of the guard was turned into the likeness of Moses.
13Thus says the Lord God of your ancestors, Throw away, each man, the abominations of his eyes, and do not defile yourselves with the idols of Egypt.
14And the children of Israel rebelled and would not hearken to Aaron at that time.
16In those days the hand of Pharaoh continued to be severe against the children of Israel, and he crushed and oppressed them until the time when God sent forth his word and took notice of them.
