The Cave of the Patriarchs (Hebrew: מערת המכפלה, Me'arat HaMachpela, Trans. "Cave of the Double Tombs"), called by Muslims the Ibrahimi Mosque or Sanctuary of Abraham (Arabic: الحرم الإبراهيمي) is a burial chamber for the early biblical Patriarchs (Adam, Abraham, Isaac, and Jacob).
The compound, located in the ancient city of Hebron, is the second holiest site for Jews (after the Temple Mount in Jerusalem) and is also venerated by Christians and Muslims who maintain that the site is the burial place of four biblical couples: Adam and Eve; Abraham and Sarah; Isaac and Rebekah; and Jacob and Leah. According to Midrashic sources, the Cave of the Patriarchs also contains the head of Esau, and according to some Islamic sources it is also the tomb of Joseph.
