Book of Numbers
Moses and the Hebrew people are escaping Egypt. They travel through Sinai. Some people complain, insult God, insult Moses. God punishes them. They send 12 spies to see what the promised land, Israel, is like. Two came back saying it is nice. Ten came back saying it is not nice and filled with "giants". So the Israelites do not go. God becomes angry and punishes them. They have to wander the desert for 40 years.
