Numbers 13:22-24

22When they had gone up through the Negev desert in the south of the land, they arrived at Hebron. That was where Ahiman, Sheshai and Talmai, the descendants of Anak, were living. They had built Hebron seven years before the Egyptians built Zoan.

23Then the men came to the valley called Eshcol. They cut a branch which had one group of grapes on it. It was so large that two men carried it between them on a pole. They also brought some other fruits called pomegranates and figs.

24They called that valley ‘Eshcol’ because of the large group of grapes that the Israelites cut down there.
