Exodus 20:3

Thou shalt have none other gods before me.

Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve.

There shall no strange god be in thee; neither shalt thou worship any strange god.

Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me,

And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.

Ye shall not go after other gods, of the gods of the people which are round about you;

And go not after other gods to serve them, and to worship them, and provoke me not to anger with the works of your hands; and I will do you no hurt.

I have sent also unto you all my servants the prophets, rising up early and sending them, saying, Return ye now every man from his evil way, and amend your doings, and go not after other gods to serve...

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.

Whose end is destruction, whose God is their belly, and whose glory is in their shame, who mind earthly things.)

Who is like unto thee, O LORD, among the gods? who is like thee, glorious in holiness, fearful in praises, doing wonders?

Trust ye in the LORD for ever: for in the LORD JEHOVAH is everlasting strength:

For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God.

Let no man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he hath not seen, vainly puffed up by his fleshly mind,

And I fell at his feet to worship him. And he said unto me, See thou do it not: I am thy fellowservant, and of thy brethren that have the testimony of Jesus: worship God: for the testimony of Jesus is...

Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me...

Whom have I in heaven but thee? and there is none upon earth that I desire beside thee.

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.

Give unto the LORD the glory due unto his name; worship the LORD in the beauty of holiness.

Ye shall not make with me gods of silver, neither shall ye make unto you gods of gold.

Then saith he unto me, See thou do it not: for I am thy fellowservant, and of thy brethren the prophets, and of them which keep the sayings of this book: worship God.

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.
