We left Moses after he murdered an Egyptian. As the story continues Pharaoh hears of the murder and tries to seize Moses and kill him for murdering an Egyptian. To save his skin, Moses flees to Midian.
While a sin with life-long consequences, I suggested that Moses' life up to this point was a season in which God fashioned a man who would share his passion for the Israelites and share God's anger at their slavery.
But that wasn't enough. Rarely is.
