Bamidbar 13:17-25

And Moshe sent them to spy out Eretz Kena'an, and said unto them, Get you up to the Negev, and go up into the mountain; And see the land, what it is like, and the people that dwelleth therein, whether they be strong or weak, few or many; And what the land is that they dwell in, whether it be good or bad; and what cities they be that they dwell in, whether in tents, or in strongholds; And what the land is, whether it be fertile or barren, whether there be 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 searched the land from the midbar of Tzin unto Rechov, as men come to Chamat. And they ascended by the south, and came unto Chevron; where Achiman, Sheshai, and Talmai, the Anak, were. (Now Chevron was built seven shanim before Tzoan in Mitzrayim.) And they came unto the Wadi Eshcol, and cut down from thence a branch with cluster of anavim echad, and they bore it between two upon a staff; and they brought of the pomegranates, and of the figs. The place was called the Wadi Eshcol, because of the cluster of grapes which the Bnei Yisroel cut down from thence. And they returned from searching of the land after arba'im days.
