Exodus is the book where we first meet Moses and the title kind of gives away the plot. Any time there’s a mass departure, whether huge swarms of people leaving the mall or thousands of people fleeing the country, we call it an exodus. And that’s exactly what exodus means: ‘going out’ or ‘departure.’ So, the story of Moses begins in the book of Exodus. But before we get to meet him, we need to understand where God’s people, Israel, were. We need to understand what they were up against. We need to grasp just how dire their situation was so that when God calls Moses to lead and deliver them, we get it.
