The Twelve Spies, 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, and is repeated with some differences in Deuteronomy 1:22–40.

The Book of Numbers is the fourth book of the Hebrew Bible and the fourth of five books of the Jewish Torah. The book has a long and complex history; its final form is possibly due to a Priestly redaction of a Yahwistic source made sometime in the early Persian period. The name of the book comes from the two censuses taken of the Israelites.
