ONE God -- Verses from Isaiah

I was reading in the book of Isaiah and was struck once again at how often God reminds us that He is the only God to be worshipped.  There is only ONE God, not two as the WMSCOG teaches.  God would not say something in the Bible that He would have to contradict later in order to reveal "Mother God" to the world.  No, that would make Him out to be a liar, which He cannot be.

The following verses are from Isaiah chapters 42-46.  Look how often God repeats it in these five chapters.
I'll include the Hebrew word used for God in each.  You can see, it doesn't matter whether you're talking about "Elohim," "El," or "Eloah," the LORD (YHWH, Jehovah) is the only one.

"I am the LORD, that is My name;
      And My glory I will not give to another,
      Nor My praise to carved images." (Is. 42:8)

“You are My witnesses,” says the LORD,
“And My servant whom I have chosen,
 That you may know and believe Me,
 And understand that I am He.
 Before Me there was no God [El] formed,
 Nor shall there be after Me.
 I,even I, am the LORD,
 And besides Me there is no savior." (Is. 43:10-11)

Thus says the LORD, the King of Israel,
    And his Redeemer, the LORD of hosts:
   "I am the First and I am the Last;
    Besides Me there is no God [Elohim]." (Is. 44:6)

"Do not fear, nor be afraid;
      Have I not told you from that time, and declared it?
      You are My witnesses.
      Is there a God [Eloah] besides Me?
      Indeed there is no other Rock;
      I know not one.’” (Is. 44:8)

I am the LORD, and there is no other;
There is no God [Elohim] besides Me.
I will gird you, though you have not known Me,
That they may know from the rising of the sun to its setting
That there is none besides Me.
I am the LORD, and there is no other; (Is. 45:5-6)

This is what the LORD says: ... "They will bow down before you and plead with you, saying, 'Surely God [El] is with you, and there is no other; there is no other god [Elohim].'" (Is. 45:14 NIV)

For thus says the LORD,
      Who created the heavens,
      Who is God [Elohim],
      Who formed the earth and made it,
      Who has established it,
      Who did not create it in vain,
      Who formed it to be inhabited:
      “I am the LORD, and there is no other." (Is. 45:18)

"Tell and bring forth your case;
      Yes, let them take counsel together.
      Who has declared this from ancient time?
      Who has told it from that time?
      Have not I, the LORD?
      And there is no other God [Elohim] besides Me,
      A just God [El] and a Savior;
      There is none besides Me.
      Look to Me, and be saved,
      All you ends of the earth!
      For I am God [El], and there is no other." (Is. 45:21-22)

"Remember the former things of old,
      For I am God [El], and there is no other;
      I am God [Elohim], and there is none like Me," (Is. 46:9)
