Exodus 20:1-6 ASV
(1)  And God spake all these words, saying,
(2)  I am Jehovah thy God, who brought thee out of the land of Egypt, out of the house of bondage.
(3)  Thou shalt have no other gods before me.
(4)  Thou shalt not make unto thee a graven image, nor any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth:
(5)  thou shalt not bow down thyself unto them, nor serve them; for I Jehovah thy God am a jealous God, visiting the iniquity of the fathers upon the children, upon the third and upon the fourth generation of them that hate me,
(6)  and showing lovingkindness unto thousands of them that love me and keep my commandments.

THEISM IS NOT 'BELIEF IN THE JEWISH GOD JESUS'.

The Israelites went to exile to Babylon because of their theism, among other rebellions against Jesus.

People do not take time to study their unbelief in order to categorize it or characterize it properly. They do not know anything of substance about unbelief either. Obviously, they lack knowledge and objective critical thinking skills.

If the professed unbelievers in the God of Abraham, Isaac, Jacob, and Moses, that is, YEHOSHUA MESSIAH YHWH aka Jesus (Luke 2:11, Matthew 1:21), were well educated in Judaism as they claim, they would have come to realize that the problem of the Israelites with God (Jesus in fact) was that they were theists and not atheists, as atheism is embedded in the 10 commandments (words).

God says in Exodus 20:3 that, 'Thou shalt be atheists before me' which means, 'Thou shalt have no other gods before me.'

Atheism (Ephesians 2:12) is 'without god' and is welcome by God according to Exodus 20:1-6. If that can be understood.

Regardless of what men believe or teach, atheism is 'without god'. 

If I am a theist (believe in any teaching of men, according to Mark 7:7, or any gods of the world) I am an idolator and, as such, I will not be saved (Revelation 14:6-12).

In truth, a theist happens to be anyone who rejects Jesus Christ the Lord (YEHOSHUA MESSIAH YHWH in Hebrew) or any of His commandments in the Jewish Bible (Ezekiel 33:13), unbeknownst to the person or not, whether that person believes in the God of the Israelites (Jesus) or not.

By default, the adversary Satan is considered to be the god of this world (2 Corinthians 4:4), of those who follow him in one counterargument in the word of Jesus, just as Adam and Eve did.

If you do not totally choose YEHOSHUA MESSIAH YHWH, you are automatically assigned to Satan and you have no control over the choice, whether you protest or not (Ezekiel 33).

Deuteronomy 4:15-20 ASV
(15)  Take ye therefore good heed unto yourselves; for ye saw no manner of form on the day that Jehovah spake unto you in Horeb out of the midst of the fire;
(16)  lest ye corrupt yourselves, and make you a graven image in the form of any figure, the likeness of male or female,
(17)  the likeness of any beast that is on the earth, the likeness of any winged bird that flieth in the heavens,
(18)  the likeness of anything that creepeth on the ground, the likeness of any fish that is in the water under the earth;
(19)  and lest thou lift up thine eyes unto heaven, and when thou seest the sun and the moon and the stars, even all the host of heaven, thou be drawn away and worship them, and serve them, which Jehovah thy God hath allotted unto all the peoples under the whole heaven.
(20)  But Jehovah hath taken you, and brought you forth out of the iron furnace, out of Egypt, to be unto him a people of inheritance, as at this day.

The confession of atheism of Jehovah God

Isaiah 45:21 ASV
(21)  Declare ye, and bring it forth; yea, let them take counsel together: who hath showed this from ancient time? who hath declared it of old? have not I, Jehovah? and there is no God else besides me, a just God and a Saviour; there is none besides me.

Exo 20:3-5
(3)  Thou shalt have no other gods before me [ATHEISM]. (4)  Thou shalt not make unto thee a graven image, nor any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth: (5)  thou shalt not bow down thyself unto them, nor serve them; for I Jehovah thy God am a jealous God, visiting the iniquity of the fathers upon the children, upon the third and upon the fourth generation of them that hate me,
