Historically, the transformation of Satan from the earlier Hebrew texts to the later ones and the New Testament ones seem to have been related to their exposure to Zoroastrianism during the Second Temple period.

During the Second Temple Period, when Jews were living in the Achaemenid Empire, Judaism was heavily influenced by Zoroastrianism, the religion of the Achaemenids.[27][8][28] Jewish conceptions of Satan were impacted by Angra Mainyu,[8][29] the Zoroastrian god of evil, darkness, and ignorance.[8] In the Septuagint, the Hebrew ha-Satan in Job and Zechariah is translated by the Greek word diabolos (slanderer), the same word in the Greek New Testament from which the English word "devil" is derived.[30] Where satan is used to refer to human enemies in the Hebrew Bible, such as Hadad the Edomite and Rezon the Syrian, the word is left untranslated but transliterated in the Greek as satan, a neologism in Greek.[30]https://en.wikipedia.org/wiki/Satan#Second_Temple_period
