Sefer haYashar, as it's known in Hebrew, is an ancient text referenced in the Bible itself (Joshua 10:13 and 2 Samuel 1:18), though the version we have today is likely a medieval work that draws upon older traditions and midrashic interpretations.
Our story centers on Esau, the brother of Jacob, and Nimrod, the mighty hunter and king of Babel. According to the Book of Jasher, after the death of Abraham, Esau was frequently out hunting. Nimrod, identified here as Amraphel (a name familiar from the story of Abraham and the kings in Genesis 14), was also a keen hunter, often accompanied by his warriors.
But there was a darkness brewing. The text tells us that "a jealousy was formed in the heart of Nimrod against Esau all the days." Why? The Jasher doesn't explicitly say, but we can infer a power struggle, a sense of rivalry between these two powerful figures.
One day, Esau is out hunting and spots Nimrod in the wilderness with only two companions. Nimrod's mighty men were also in the field, but they were far away. Seizing the opportunity, Esau ambushes Nimrod, drawing his sword and cutting off his head! A brutal act, to be sure.
Esau then fights and kills Nimrod's two companions. The cries of these men are heard by Nimrod's warriors in the distance. They rush to the scene, only to find their king and his companions dead. Seeing them approach, Esau flees.
But he doesn't leave empty-handed. Esau takes Nimrod's valuable garments, garments that Nimrod's father had bequeathed to him, garments that had, according to the text, helped Nimrod gain power over the land. Esau hides these garments in his house.
Exhausted and grief-stricken from the fight, Esau stumbles into his brother Jacob's presence. "Behold I shall die this day," he cries, "and wherefore then do I want the birthright?"
Ah, the birthright. The inheritance, the blessing, the future. Jacob, ever the pragmatist, seizes the moment. He acts "wisely," the text says, and Esau sells his birthright to Jacob. Not only that, but Esau also sells his portion in the Cave of Machpelah, the burial ground Abraham had purchased (Genesis 23). Jacob documents the entire transaction, sealing it with witnesses.
And what of Nimrod? His men carry his body back to the city and bury him. The Book of Jasher tells us Nimrod lived for 215 years and reigned for 185. He died, the text emphasizes, "by the sword of Esau in shame and contempt," and that the seed of Abraham caused his death, as Nimrod had seen in a dream.
The aftermath is significant. Nimrod's kingdom fractures, and the lands he controlled are returned to their original rulers. The people of Nimrod's house are enslaved.
What are we to make of this story? It’s a violent tale of power, jealousy, and opportunity. It paints Esau as a cunning and ruthless figure, not just the simple hunter of popular imagination. And it highlights Jacob's shrewdness, his ability to recognize and seize opportunities, even in the midst of tragedy. It's a far more complex and nuanced picture than we often get.
The Book of Jasher provides us with a glimpse into the rich tapestry of Jewish tradition, showcasing how stories evolve, adapt, and offer different perspectives on familiar narratives. It reminds us that even the most well-known figures have hidden depths, and that the past is never quite as simple as it seems.
