According to the religious narrative of the Hebrew Bible, the Israelites' origin is traced back to the biblical patriarchs and matriarchs Abraham and his wife Sarah, through their son Isaac and his wife Rebecca, and their son Jacob (who was later called Israel, whence they derive their name) with his wives Leah and Rachel and the handmaids Zilpa and Bilhah. The Israelites are the ethnic stock from which modern Jews and Samaritans originally trace their ancestry. Modern Jews are named after and also descended from the southern Israelite Kingdom of Judah, particularly the tribes of Judah, Benjamin, Simeon and partially Levi. Many Israelites took refuge in the Kingdom of Judah following the collapse of the Kingdom of Israel.
