“The Unitarian may be tempted to say that verse 11 proves that the man talking to her was not Yahweh and, thus, we are not confronted with two Yahwehs. But in verse 13, Hagar leaves no doubt as to the identity of the Messenger who is talking with her. In verse 13, Hagar calls upon the name of Yahweh. But is it the Yahweh referred to in verse 11, or the Yahweh who is standing there talking with her? Which Yahweh is it?”(6)Here Morey suggests the Unitarian is tempted to say “we are not confronted with two Yahwehs.” This is obviously the view that Morey holds and one he feel Unitarians challenge. What is this belief? The one that there is more than one Yahweh. We will discuss monotheism later in this dicussion but If this is not enough trinitiarans also say that each of these Yahweh’s are separate or distinct persons. Each complete with mind and center of consciousness. Each possessing unique attributes and not the same as the other
"Linguistically, it is certainly possible to support the rendering "Yahweh our God is one single Yahweh"; that is to say, he is not a God who can be split up into various divinities or powers, like the Baals of Tyre, of Hazor and or Schechem, etc., but one who unites himself as a single person everything which Israel thought of as appertaining to God."(7)Ezekiel 33:24 records, “Son of man, the inhabitants of these waste places in the land of Israel keep saying, ‘Abraham was only one man, yet he got possession of the land; but we are many; the land is surely given us to possess.’ (ESV) In this text, the word "one" is echad and is used to refer to Abraham as one man or one person. Occasionally echad is used to modify a collective noun (e.g. “one bunch”; “one pair”; “one herd”) but its actual meaning never changes. It still means “one” and only “one.” Any plurality is found in the collective noun, not in the word echad. Compare the following translations of Deuteronomy 6:4. Remember, “LORD” is representative of the Hebrew word for Yahweh. It is obvious that there can only be one.
