Deut: 32: 36-41
36) For their rock is not as our Rock,
even our enemies themselves being judges.
37)For their Vine is of the Vine of Sodom,
and of the fields of Gomorrah.
Their grapes are grapes of gall,
their clusters are bitter!
38) YAHWEH will judge his people, and have compassion...
39) And he shall say, "Where are their gods?
Their 'Rock' in whom they trusted?
40) Those who ate the fat of their sacrifices?
and drank the wine of their Drink offering?
Oh, let them rise up and help you, and be your protection!
41)See now that I myself am 'HE',
and there are no other deities with me."
Zech 14: 1 & 9
1)Behold, the day of YAHWEH comes,
and your plunder shall be divided among you...
9)And YAHWEH shall be king over all the earth on that day,
and 'YAHWEH' shall be his one and only name.
Psalm 83:16-18
16) Fill their faces with shame so that they may seek your name, O YAHWEH.
17) Let them be confounded and troubled forever, and be put to shame, and perish,
18)so that men may know that you, whose name is 'YAHWEH' alone, are the most high over all the earth.
ISAIAH 43:10-12
10) "You all are my witnesses and my Servant whom I have chosen,
so that you may know and believe in me,
and understand that I am HE.
Before me no other god was formed,
and there will be no one after me!
11) I, yes I, am YAHWEH.
And apart from me there is no other saviour.
12) I have revealed and redeemed and proclaimed.
I did this, and not some other among you."
Isaiah 44:6-9
6) Thus says YAHWEH, the King of Israel,
and his redeemer, YAHWEH of hosts:
"I am the first, and I am the last,
and there is no deity beside me.
7) "And who is like me? Let him make the claim,
and declare and tell me of the things that have happened since I chose the ancient people,
and the things that are coming,
and what will come!
Let them predict them!
8) Fear not, neither be afraid:
for, have not I told you from that time, and have declared it?
9) You are my very witnesses.
Is there a deity beside me?
Indeed there is not.
I know no other Rock.
10) They that make a graven image are all vain men,
and their delectable things shall not profit;
for they are their own witnesses,
and they see not,
nor know,
else they would be ashamed.
ISAIAH 45:5-6
I am YAHWEH, and there is no one else,
there is no deity beside me.
I strengthened you, though you did not acknowledge me,
So that they may know,
from the rising of the sun,
and from the west,
that there is no one beside me.
I am YAHWEH, and there is no one else.
Isaiah 45:19-22
19)I have not spoken in secret,
in a dark place of the earth.
I did not say to the descendents of Jacob,
"You seek me in vain",
I, YAHWEH, speak righteousness,
I declare things that are right.
20) Assemble yourselves and come,
draw near together, you who have escaped from the Gentile Nations.
They who set up the wood of their graven image,
and pray to a god that cannot save,
have no knowledge.
21)Tell all, and bring them near.
Yes, let them take counsel together:
Who has declared this from ancient time?
Who has told it from that time?
Have not I, YAHWEH?
And there is no other deity beside me, a just god and a saviour.
There is no one beside me.
22) Look to me, and be saved,
all the ends of the earth.
For I am YAHWEH, and there is no one else.
Hosea 13:4
Yet I am YAHWEH, your god from the land of Egypt, and you shall know no god but me,
for there is no saviour beside me.
Numbers 23:19
God is not a man, else he might lie,
neither is God the Son of Man, else he might change his mind.
Has he said, and shall not do?
or has he spoken, and shall not make it so?
And besides all the scripture that says God is ONE, where in the OT, do you find any indication that the messiah would actually BE GOD? The messiah was to be one annointed by God, but not to actually BE God Himself.
And apart from me there is no other saviour.
Who went up to heaven, and cometh down?
Who hath gathered the wind in his fists?
Who hath bound waters in a garment?
Who established all ends of the earth?
What [is] His name? and what His son's name?
Surely thou knowest!
Proverbs 30:4
