I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage.
Thou shalt have no other gods before me.
Unto thee it was shewed, that thou mightest know that the Lord he is God; there is none else beside him.

Hear, O Israel: The Lord our God is one Lord:
And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.
Now therefore fear [reverence] the Lord, and serve him in sincerity and in truth: and put away the gods which your fathers served on the other side of the flood, and in Egypt; and serve ye the Lord.
And if it seem evil unto you to serve the Lord, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the Lord.
II Samuel 7:22:
Wherefore thou art great, O Lord God: for there is none like thee, neither is there any God beside thee, according to all that we have heard with our ears.
Thus saith the Lord the King of Israel, and his redeemer the Lord of hosts; I am the first, and I am the last; and beside me there is no God.
Fear ye not, neither be afraid: have not I told thee from that time, and have declared it? ye are even my witnesses. Is there a God beside me? yea, there is no God; I know not any.
I am the Lord, and there is none else, there is no God beside me: I girded thee, though thou hast not known me:
That they may know from the rising of the sun, and from the west, that there is none beside me. I am the Lord, and there is none else.
For thus saith the Lord that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the Lord; and there is none else.
Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the Lord? and there is no God else beside me; a just God and a Saviour; there is none beside me.
And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all?
And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord:
And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
And the scribe said unto him, Well, Master, thou hast said the truth: for there is one God; and there is none other but he.
And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
I Corinthians 8:4-6:
As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one.
For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,)
But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
There is one body, and one Spirit, even as ye are called in one hope of your calling;
One Lord, one faith, one baptism,
One God and Father of all, who is above all, and through all, and in you all.
I Timothy 2:5:
For there is one God, and one mediator between God and men, the man Christ Jesus.
Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
