The flow and influence of religions is as communicative as humanity itself, remember, folks, we , as a species, are a social bunch. Judaism, the progenitor of all other Abrahamic faiths such as Christianity and Islam, was in turn influenced by Eastern religions. When Israel was conquered by the Babylonians, and then by the Persians, the Hebrew people where influenced by Zoroastrianism, to which some religious festivals and rituals, as well as in theology, too. Zoroastrianism was the only other religion of its time (approx 1700-1000 BCE) to believe in a single omniscient and supreme being besides Judaism; at a time that the Hebrew tribes were still forming their beliefs. Those beliefs had an opportunity to influence one another in the sixth century, BCE, when the tribe of Judah was exiled to Babylon by Nebuchadnezzar (hanging gardens' fame), where their leading citizen, Daniel (of the Lion's Den Fame) interacted with the Zoroastrian king of Anshan (Iran), Cambyses I, his son, Cyrus the Great and Cyrus' successor, Darius the Great.
It was at that time, when the first ten books of the Bible were being transcribed from the tribe's oral history to text, that many Zoroastrian precepts were thought to have entered the belief systems of the tribe of Judah in Babylon. As specified above, Zoroastrianism is thought to have greatly influenced Judaism, specifically through the prophet Daniel's close association with the Achaeamenid kings (Cambyses I, Cyrus the Great, Cambyses II and Darius the Great).
