One of the first names of the God of Israel was El, (e.g., Gen 33:20) the main God of the Canaanites and Phoenicians. http://en.wikipedia.org/wiki/Phoenicia
The compound name Ēl ‘Elyōn 'God Most High' occurs in Genesis 14.18–19 as the god whose priest was Melchizedek (King of Righteousness, King of Jerusalem). The form appears again almost immediately in verse 22, used by Abraham.
It has been suggested that the reference to 'Ēl ‘Elyōn maker of heaven and earth' in Genesis 14:19 and 22 reflects the belief that ‘Elyōn was progenitor of Ouranus and Gê, as suggested in Philo of Byblos's account of Phoenician History.
