The big story in Parashat Shelah is the story of the spies.  The people are nearing the Land of Canaan, and Moshe sends ahead men, one from each tribe, to cross the border, check things out, and then bring back a report.  So they head out for 40 days, return safely—and, at first, all seems well.  They confirm that the land, as promised, “flows with milk and honey” (Numbers 13:27).  But then the conversation turns.  They begin to spill out all kinds of fears: the cities are fortified, the people are gigantic, and the land… “devours its inhabitants” (Numbers 13:32).
