Satan was privy to the heavenly councils...see the book of Job
Also he began studying scripture intently as soon as they were written. Satan is familiar with all the prophecies about Messiah. He caused confusion and misunderstanding among the rabbis within judaism about who the messiah is...he helped them come up with perverted interpretations of scripture which recognize the messiah as a conquering King but not a suffering servant who would come to liberate them from the tyranny of sin. Also Satan hates mankind...He knows God has a special role for humanity which transcends even the angels. This fills him with rage and resentment because he wants to be number one. That is why he has been preparing the world for his representative (the Antichrist) to rise to power ever since the days of Nimrod. This false messianic figure is the perpetually dieing god who is resurrected. The whole pagan calendar is based on him. In lucifarian witchcraft they teach it was Lucifer (nimrod) who they say was the serpent in the garden actually came to liberate mankind and deliver them from the tyranny of the God of the bible who they believe is like Satan. So everything is reversed. Since they are dualists some are both Lucifarians and Satanists (two sides of the same coin like yin and yang)...this is also why masonic lodges always have the checkerboard pattern on the floors. The God of freemasonry is the god of fusion (Baphomet...which represents Lucifer) they are dualists like the Templars before them and the Gnostics. They are all lucifarians...followers of Nimrod.
The egyptian religion came directly from babylon...the names got changed and they developed their own unique style of artwork but their belief system was essentially the same...it revolved around death and the immortality of the soul. Their chief deity was the Sun god Ra but also very prominent was the worship of the dead and the afterlife which was presided over by Anubis or Osiris...the god of the underworld and resurrection...their concept of resurrection is not the biblical concept though it is really re-incarnation. They believe Osiris went down into the underworld and was saved by his goddess sister Isis and brought back to life by the power of magic...he was reincarnated as his son Horus who lost one eye in a battle with seth (remember the all seeing eye on the dollar bill)...horus is described the same way as the Catholic Jesus (not the biblical one) and Seth is described in a similar way to Satan. So here you have a perversion of the prophecy in Genesis 3:15 about the seed of the woman being injured in battle but crushing the serpents head.
