, Set was incorporated into the early mythology of Christianity as the devil (the serpent Apophis has also been suggested as contributing to this figure's development). Set's relationship to darkness and wickedness, as well as the color red and the popular image of him as a red-haired beast, all leant themselves to the iconography of the Christian Satan. Like Satan, he brought about the end of paradise and was cast out of the land of the gods for rebelling against harmonious rule. His association with deceit, cunning, war, destruction and close connection with the serpent also worked well in fashioning the Christian concept of the great supernatural deceiver of human beings, who swore eternal enmity with God.
In the gospels of Matthew, Mark, and Luke, Jesus is tempted by Satan in the desert (or, in Matthew, in "the wilderness"), and the earlier figure of Set was strongly associated with deserts and the unknown lands beyond Egypt's borders (see Matthew 4:1-11, Mark 1: 12-13, and Luke 4:1-13). Set continued to play the role he had been given by the Osiris myth in a whole new context and belief system: as the deceiver and adversary of human beings, responsible for their suffering in a world originally created as a paradise
