He can't stay—he's a hunted man. He didn't want to kill the guard—an accident. The sight of the guard's broken body will haunt his dreams for a long time. His lungs scream for air, muscles clench with cramps as he flees Egypt, the land he once called "home". But leaving Egypt meant leaving Rameses—a terrible sacrifice. To escape the lifetime of lies and land of abiding cruelty against the Hebrews meant parting from the man he still called brother, even now. He hates to see his brother's confusion, the grief behind his eyes.
"Goodbye brother."
Moses runs.
