The Twelve Spies (Hebrew: שנים עשר המרגלים), as recorded in the Book of Numbers, were a group of Israelite chieftains, one from each of the Twelve Tribes, who were dispatched by Moses to scout out the Land of Canaan for 40 days as a future home for the Israelite people, during the time when the Israelites were in the wilderness following their Exodus from Ancient Egypt. The account is found in Numbers 13:1-33.
God had promised Abraham that there would be a Promised Land for the nations to come out of his son, Isaac. The land of Canaan which the spies were to explore was the same Promised Land. Moses asked for an assessment of the geographical features of the land, the strength and numbers of the population, the agricultural potential and actual performance of the land, civic organization (whether their cities were like camps or strongholds), and forestry conditions. He also asked them to be positive in their outlook and to return with samples of local produce.
When ten of the twelve spies showed little faith in the doom and gloom report they gave about the land, they were slandering what they believed God had promised them. They did not believe that God could help them, and the people as a whole were persuaded that it was not possible to take the land. As a result, the entire nation was made to wander in the desert for 40 years, until almost the entire generation of men had died.Joshua and Caleb were the two spies who brought back a good report and believed that God would help them succeed. They were the only men from their generation permitted to go into the Promised Land after the time of wandering.
God had promised the Israelites that they would be able to conquer the land with its indigenous Canaanite nations. Moses instructed the spies to report back on the agriculture and lay of the land. However, during their tour, the spies saw fortified cities and resident giants, which frightened them and led them to believe that the Israelites would not be able to conquer the land as God had promised. Ten of the spies decided to bring back an unbalanced report, emphasizing the difficulty of the task before them.
