"It is highly likely that Abraham's God was El, the High God of Canaan. The deity introduces himself to Abraham as El Shaddai (El of the Mountain), which was one of El's traditional titles. Elsewhere he is called El Elyon (The Most High God) or El of Bethel. The name of the Canaanite High God is preserved in such Hebrew names as Isra-El or Ishma-El. They experienced him in ways that would not have been unfamiliar to the pagans of the Middle East. We shall see that centuries later Israelites found the mana or "holiness" of Yahweh a terrifying experience. On Mount Sinai, for example, he would appear to Moses in the midst of an awe-inspiring volcanic eruption, and the Israelites had to keep their distance. In comparison, Abraham's god El is a very mild deity. He appears to Abraham as a friend and sometimes even assumes human form. This type of divine apparition, known as an epiphany, was quite common in the pagan world of antiquity."
