Jacob had twelve sons and at least one daughter, by his two wives, Leah and Rachel, and by their handmaidens Bilhah and Zilpah. Jacob's twelve sons, named in Genesis, were Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph, and Benjamin. His only daughter mentioned in Genesis is Dinah.
JOB 42:13-15: He also had seven sons and three daughters. And he called the name of the first Jemimah, the name of the second Keziah, and the name of the third Keren-Happuch. In all the land were found no women so beautiful as the daughters of Job; and their father gave them an inheritance among their brothers.
