sorry, naomi, I missed your earlier post. The Bible says the Lord told Abraham his people could have the Holy Land. In general it was Yahweh (Jehovah), the Judean god, who talked to people that way; Elohim, the Israelite god, was more remote: he created the universe, Yahweh created man and other beasties, and their creation stories run side by side in Genesis.
The two states merged and so did their gods, but not till after Abraham's time. So it sounds more likely to me that it was Jehovah.
