The Messiah in Moses and The Prophets

Excerpt-At the period of the legation of Moses, the word Elohim was in familiar use in Egypt and among the Israelites as the designation of the object of religious homage; very probably it was the only name of God known to the people generally. Moses accordingly, in the first two chapters of Exodus, which probably were written before the book of Genesis, employs that name only. The third chapter opens with the announcement of the Messenger Jehovah appearing in the bush, and in its progress applies to him indifferently the names Elohim and Jehovah; and in the fourth and ensuing chapters, the same, and Adonai and El-Shadai, but most frequently Jehovah.
