We are the Tribe of Judah. JACOB’S SONS First, the tribes of the Old Testament for clarity are really 13 tribes—that’s right!You see, the 12 original tribes all came from the 12 sons of Jacob, whom the Lord had later renamed Israel. When Joseph’s older brothers sold him into slavery, it was the beginning of a long and painful separation from his family. After reuniting with his father, Jacob promised to compensate for Joseph’s years of separation by adopting two sons, Manasseh and Ephraim, as his own to be numbered with his sons in place of Joseph.Â
