Before Judaism, Persian religion was spread across Middle East.
Persian were ruler of land from today’s Afghanistan to Egypt.
Jew i.e. Hebrew speaking people were polytheist, not monotheist.They didn’t have their own Nation.
Jew patriarch Abram was an Airyanem (Iranian) by origin. http://www.ekurd.net/mismas/articles/misc2010/7/state4071.htm .
Abram and his wife Sarai were Persian couple. Abram wanted to establish his own religion.
He established his new religion out of his ancestral Persian religion.
At that time, many Hebrew speaking people became his followers.
Further, his religion known as Judaism.
He adopted monotheism, God-Satan, resurrection, heave-hell etc. from Persian religion. He introduced prayer in the morning. His son Isaac introduced prayer in the afternoon, and His grand-son Jacob added one at night. http://www.chabad.org/library/article_cdo/aid/682091/jewish/The-Three-Daily-Prayers.htm
During Yom Kippur, Jew offer prayer at five times as Persian used to pray at five times.

Every synagogue has Flame (Fire) symbol which had taken from Persian religion as Persian known as fire-worshiper. In synagogue, in front of and slightly above the Ark, you will find the ner tamid, the Eternal Lamp. This lamp symbolizes the commandment to keep a light burning in the Tabernacle outside of the curtain surrounding the Ark of the Covenant. (Ex. 27:20-21). http://www.jewfaq.org/shul.htm This lamp is nothing but Fire symbol taken from Persian Religion.
Skull cap, uniform of priest was adopted from Persian religion.
Jew were following the tradition established by Abram and carry forward by Issac, Jacob and others.
The changed happened when Moses the Chief Prophet of Jew wrote Torah. He changed Persian name of Abram and Sarai to Hebrew name Abraham and Sarah. In Hebrew, Abraham means “leader of Nations”.
Moses wanted every nation should implement ideal of Torah. (Greek-Roman and Arab implemented Ideal of Torah in their nation in the name of Christianity and Islam respectively)
While writing Torah, Moses discontinued root of Persian religion. He wrote story of Adam, creation, and link it to Abraham. He described his religion came directly from God. He sidelined Persian religion and shown his religion is unique, not plagiarize.
Jew believes, G-d revealed the entire Torah to Moses. The entire Torah included the first five books of the Bible (Genesis, Exodus, Leviticus, Numbers and Deuteronomy).
On basis of Torah, Jew created Halakha (the holy law) and implemented it in Israel.
Judaism created Israel, the nation of Jew. Jew believes, this land is given by God to Jew only.
They wrote 613 commandments. http://www.jewfaq.org/613.htm .
The main aspect of Judaism is to establish Israel, the home for Hebrew speaking people. Earlier Jews were pluralistic, polytheist and idol-worshipers. They impressed by monotheism of Persian. After adopting monotheism they established their nation, Israel.
Further, Judaism split in three i.e. Issaci-Jew, Messianic-Jew and Ishmaeli-Jew.
Issaci-Jew known as mainstream Judaism
Messianic-Jew known as Christian (in Greek-Messiah means Christ and follower of Christ are Christian)
Ishmaeli-Jew known as Islamic/Muslim.
