Keil & Delitzsch

The spies also came into the valley of Eshcol, where they gathered pomegranates and figs, and also cut down a vine-branch with grapes upon it, which two persons carried upon a pole, most likely on account of its extraordinary size. Bunches of grapes are still met with in Palestine, weighing as much as eight, ten, or twelve pounds, the grapes themselves being as large as our smaller plums (cf. Tobler Denkbltter, pp. 111, 112). The grapes of Hebron are especially celebrated. To the north of this city, on the way to Jerusalem, you pass through a valley with vineyards on the hills on both sides, containing the largest and finest grapes in the land, and with pomegranates, figs, and other fruits in great profusion (Robinson, Palestine, i. 316, compared with i. 314 and ii. 442). This valley is supposed, and not without good ground, to be the Eshcol of this chapter, which received its name of Eshcol (cluster of grapes), according to Num 13:24, from the bunch of grapes which was cut down there by the spies. This statement, of course, applies to the Israelites, and would therefore still hold good, even if the conjecture were a well-founded one, that this valley received its name originally from the Eshcol mentioned in Gen 14:13, Gen 14:24, as the terebinth grove did from Mamre the brother of Eshcol.
