This part camps out in the second book of the bible, Exodus. We explore the story of Moses, Pharaoh, and the liberation of the Israelites that all culminates in the night of Passover. This was one of the most important foundation stories for the Israelite people in ancient times, and its crucially important for understanding Jesus. He timed his arrival into Jerusalem for the Passover feast and at the Last Supper he used the Passover symbols to explain the meaning of his coming death.
From there we move on to learning about the covenants between God and Israel and the giving of the Ten Commandments at Mount Sinai. This is, again, a core idea that Jesus picked up and developed in his own teaching .
