Some Jewish traditions regarding Adam place him in Hebron after his expulsion from Eden. Another has Cain kill Abel there. A third has Adam and Eve buried in the cave of Machpelah. A Jewish-Christian tradition had it that Adam was formed from the red clay of the field of Damascus, near Hebron. A tradition arose in medieval Jewish texts that the Cave of the Patriarchs itself was the very entrance to the Garden of Eden. During the Middle Ages, pilgrims and the inhabitants of Hebron would eat the red earth as a charm against misfortune. Others report that the soil was harvested for export as a precious medicinal spice in Egypt, Arabia, Ethiopia and India and that the earth refilled after every digging. Legend also tells that Noah planted his vineyard on Mount Hebron. In medieval Christian tradition, Hebron was one of the three cities where Elizabeth was said to live, the legend implying that it might have been the birthplace of John the Baptist.
