The relationship between God, Moses and the Children of Israel was very interesting. The children of Israel were always looking back to Egypt, rather than forward to the promised land. "Oh that we had stayed in Egypt" was a common cry. They said this when Pharaoh trapped them against the banks of the Red Sea, when they were short of water, when they had no fun, when they were tired of manna, when the way was too hard, and when they feared those in Canaan. It got to the point where God was ready to destroy the house of Israel, but Moses convinced him not to do so. Instead he determined that the current generation would all die off before they would enter the promised land, and that is what happened except for Joshua and Caleb.
Follow the prophet.
Robert D. Hales, walk by faith.
What is even more incredible is the constant reminders of Jesus Christ in this story. We see a type of Jesus in the Passover. The lamb without blemish, and the blood on the doorway point to Christ, the manna or bread of life reminds us of Jesus, and the snake on a staff, to which the people must look to live also reminds us of Jesus.
