The Cave of the Machpela: "Southward from Jerusalem, where are buried Abraham, Isaac, and Jacob, and their wives Sarah, Rebecca and Leah. A solemn sight, the cave itself is resplendent with ancient wall stones, the Mosque, and the cenotaphs." Source: World Guide for the Jewish Traveler by Warren Freedman, E.P. Dutton Inc, NY 1984.
