The Tribe of Joseph is not usually listed with the Hebrew tribes although Joseph is one of Jacobs twelve sons, the eldest of Rachel. It is sometimes referred to as the House of Joseph. Rather, the two tribes founded by his sons Ephraim and Manasseh are listed separately.
The Ten Lost Tribes are those from the northern Kingdom of Israel who were deported by the Assyrians in the 8th century BC to Khorason. In Jewish popular culture, the ten tribes disappeared from history, leaving only the tribes of Benjamin and Judah and Levi who evolved into the modern day Jews.
