Transcription: It took 40 years in Egypt and 40 years in the desert to prepare Moses for the leadership role. God's announcement, or call, was an encounter Moses would never forget. A fiery bush, a voice from nowhere, God introducing himself by name. I am the God of Abraham, Isaac, and Jacob, he said, drawing a connection to all the promises that had gone before. And now the time for action had arrived. Moses was his hand-picked choice to lead that mob from slavery in Egypt to freedom in the Promised Land.
