The patriarchs (Hebrew: אבות ʾAvot, "fathers") of the Bible, when narrowly defined, are Abraham, his son Isaac, and Isaac's son Jacob, also named Israel, the ancestor (according to the Abrahamic tradition) of the Israelites. These three figures are referred to collectively as "the patriarchs", and the period in which they lived is known as the patriarchal age.
Judaism, Christianity, and Islam hold that the patriarchs, along with their primary wives, known as the matriarchs (Sarah, Rebekah and Leah), are entombed at the Cave of the Patriarchs, a site held holy by the three religions. Rachel, Jacob's other wife, is said to be buried separately at what is known as Rachel's Tomb, near Bethlehem, at the site where she is believed to have died in childbirth.
