Before his death, Jacob adopted Joseph’s two sons (Ephraim and Manasseh) as his own (Gen. 48:5). Later, Ephraim and Manasseh would each receive an allotment of the land and thus Joseph received a double portion, the birthright of the firstborn (Deut. 21:15-17). Reuben, the firstborn would be stripped of his birthright due to his sin of laying with Bilhah, Jacob’s concubine (Gen. 35:22 cf. 49:4).
