The Sabbath Commands - You Are Not Slave Drivers

To observe the Sabbath is also to remember not just that you are no longer slaves, but to never become a slave driver yourself. As long as you're sabbathin, it's hard for you to advance your idolatry or injustice too far,. But as later generations forgot Sabbath, they forgot who they were. So they fell into idolatry and injustice in the life of the community. They slowly over the course of the story became just like Egypt. The liberated oppressed became oppressors themselves.
