'Rebel' in the Bible

but I -- I say to you, that every one who is angry at his brother without cause, shall be in danger of the judgment, and whoever may say to his brother, Empty fellow! shall be in danger of the sanhedrim, and whoever may say, Rebel! shall be in danger of the gehenna of the fire.

"Brother will hand brother over for execution, and a father his child. Children will rebel against parents and have them put to death.
