Genesis 13:18 has Abraham settling by 'the great trees of Mamre'. The original Hebrew tradition appears, to judge from a textual variation conserved in the Septuagint, to have referred to a single great oak tree, which Josephus called Ogyges. Mamre may have been an Amorite, a tribal chieftain after whom a grove of trees was named. Genesis connected it with Hebron or a place nearby that city. Mamre has frequently been associated with the Cave of the Patriarchs. According to one scholar, there is considerable confusion in the Biblical narrative concerning not only Mamre, but also Machpelah, Hebron and Kiryat Arba, all four of which are aligned repeatedly. In Genesis, Mamre is also identified with Hebron itself (). The Christian tradition of identifying a ruined site surrounded by walls and called in Arabic "Rāmet el-Ḥalīl" ('Hill of the Friend', meaning: "the friend of God", i.e. Abraham), with the Old Testament Mamre, goes back to the earliest Christian pilgrims in the 4th century CE, and connect to a tradition from the time of Herod (1st century BCE).
