God had had told the Israelites that He would drive all the people out before them but they still said:

Num 14:1-4
14:1 The whole community was in an uproar, wailing all night long. 2 All the People of Israel grumbled against Moses and Aaron. The entire community was in on it: "Why didn't we die in Egypt? Or in this wilderness? 3 Why has GOD brought us to this country to kill us? Our wives and children are about to become plunder. Why don't we just head back to Egypt? And right now!"
4 Soon they were all saying it to one another: "Let's pick a new leader; let's head back to Egypt."

Was that smart? Weren't they relying on humans instead of God?
