The Book of Jasher 27
4And on a certain day Esau went in the field to hunt, and he found Nimrod walking in the wilderness with his two men.
5And all his mighty men and his people were with him in the wilderness, but they removed at a distance from him, and they went from him in different directions to hunt, and Esau concealed himself for Nimrod, and he lurked for him in the wilderness.
6And Nimrod and his men that were with him did not know him, and Nimrod and his men frequently walked about in the field at the cool of the day, and to know where his men were hunting in the field.
7And Nimrod and two of his men that were with him came to the place where they were, when Esau started suddenly from his lurking place, and drew his sword, and hastened and ran to Nimrod and cut off his head.
8And Esau fought a desperate fight with the two men that were with Nimrod, and when they called out to him, Esau turned to them and smote them to death with his sword.
9And all the mighty men of Nimrod, who had left him to go to the wilderness, heard the cry at a distance, and they knew the voices of those two men, and they ran to know the cause of it, when they found their king and the two men that were with him lying dead in the wilderness.
12And he said unto his brother Jacob, Behold I shall die this day, and wherefore then do I want the birthright? And Jacob acted wisely with Esau in this matter, and Esau sold his birthright to Jacob, for it was so brought about by the Lord.
14And Jacob wrote the whole of this in a book, and he testified the same with witnesses, and he sealed it, and the book remained in the hands of Jacob.
15And when Nimrod the son of Cush died, his men lifted him up and brought him in consternation, and buried him in his city, and all the days that Nimrod lived were two hundred and fifteen years and he died.
16And the days that Nimrod reigned upon the people of the land were one hundred and eighty-five years; and Nimrod died by the sword of Esau in shame and contempt, and the seed of Abraham caused his death as he had seen in his dream.
17And at the death of Nimrod his kingdom became divided into many divisions, and all those parts that Nimrod reigned over were restored to the respective kings of the land, who recovered them after the death of Nimrod, and all the people of the house of Nimrod were for a long time enslaved to all the other kings of the land.
