Mamre was an Amorite who lived in the land of Canaan, in the area called Hebron in what would much later be the kingdom of Judah. He and his brothers, Aner and Eshcol, were friends of Abram. To dwell in "the oak groves of Mamre" is to perceive the affections aroused by delight in the early simple knowledges gathered in childhood through the senses; oaks refer knowledge and Mamre indicates its delightful quality. In representative language, this describes a state that Jesus went through in early childhood, and at a different level, a state that we pass through too.
