Jacob, who was called Israel, spoke a word over each of his sons from his death bed. He bestowed a double portion to Joseph, giving his two sons, Ephraim and Manasseh, equal standing to his other sons. And so, when the twelve tribes of Israel move out of Egypt 400 years later, two of the twelve tribes are called Ephraim and Manasseh. The last words of Jacob are explanatory and prophetic. They explain the origin of the twelve tribes of Israel, and they predict the coming of the Messiah to the tribe of Judah (Gen. 49:8-12). Genesis is a book of beginnings. It describes the creation and the fall of humanity. It begins the story of God’s rescue.
