A quick fast forward through the generations after Jacob (no begats, phew!) and then we meet Moses
* The current Pharaoh decides that the Hebrews would make really good slaves, so sets them to work on building things. He also thinks there are too many of them, so demands that every male child is killed at birth. These sort of acts are actually appear to be bad for once, now that it's not one of the 'chosen' people or God himself who are committing them.
* Moses' mother manages a good scheme, she put Moses in a basket and floats him down the river, then an Egyptian princess sees the baby and gets a Hebrew woman to nurse him for pay. His mother is that woman, she gets to look after her baby and get paid for it, pretty good deal that!
* God always appeared in person to Abraham, Isaac and Jacob, but now he has to utilise a burning bush in order to tell Moses to free the Hebrews from slavery. It's funny that these people are always alone when they have a conversation with God, very convenient. So now God promises to kill any Egyptians who prevent the slaves from escaping, because it's OK when God does it.
