Ramban said that the twelve spies were listed in order of personal greatness or social rank. Caleb was third and Joshua fifth. Whether this is true or not, the spies were not weak and fearful men, but respected leaders who had witnessed God's power. What happened to their souls that they would doubt God despite all they experienced? "The people are strong and the cities are great, but with God, we will prevail." This is what they should have said.
Numbers 13
