Satanael refused to bow.
The Life of Adam and Eve imagines the scene on the sixth day of creation. God has formed Adam, breathed life into him, and placed him before the angels. Then comes the command that breaks the heavens open: honor the human being made in the divine image.
Michael bows first. Satanael will not. He was formed before Adam, he says, and fire should not bend before dust. Other angels follow him. The refusal is not a rival kingdom declaring war on God. It is pride, wounded rank, and the terror of watching a lower creature receive honor from above.
God casts Satanael down to earth. Adam receives the place Satanael lost. From that moment, the accuser looks at Eden and sees his own humiliation walking in human skin.
That is why the story turns toward the serpent. Satanael cannot strike God, so he strikes the creature God chose. He studies Adam's joy, waits for Eve, and uses the tree as his revenge.
The Jewish force of the tale is not dualism. Satanael does not become God's equal. He remains a punished angel whose power is limited by heaven. The danger is closer than cosmic rebellion: honor can curdle into envy, and envy can make even an angel forget his place.
