The Twelve Tribes of Israel (Hebrew: שִׁבְטֵי־יִשְׂרָאֵל, romanized: Šīḇṭēy Yīsrāʾēl, lit. 'Staffs of Israel') are, according to Hebrew scriptures, the descendants of the biblical patriarch Jacob (also known as Israel), who collectively form the Israelite nation. The tribes were through his twelve sons through his wives, Leah and Rachel, and his concubines, Bilhah and Zilpah. In modern scholarship, there is skepticism as to whether there ever were twelve Israelite tribes, with the use of the number 12 thought more likely to signify a symbolic tradition as part of a national founding myth,[1] although some scholars disagree with this view.[2]
