Numbers 13:2, 17-21

Send thou men, that they may spy out the land of Canaan, which I give unto the children of Israel: of every tribe of their fathers shall ye send a man, every one a prince among them.

And Moses sent them to spy out the land of Canaan, and said unto them, Get you up this way by the South, and go up into the hill-country: and see the land, what it is; and the people that dwell therein, whether they are strong or weak, whether they are few or many; and what the land is that they dwell in, whether it is good or bad; and what cities they are that they dwell in, whether in camps, or in strongholds; and what the land is, whether it is fat or lean, whether there is wood therein, or not. And be ye of good courage, and bring of the fruit of the land. Now the time was the time of the first-ripe grapes. So they went up, and spied out the land from the wilderness of Zin unto Rehob, to the entrance of Hamath.
