“Eshcol, Valley of” From Concise Bible Dictionary:
Called both a brook and a valley because the one ran in the other, now called a Wady, which are very numerous in Palestine. It was near Hebron, the place explored by the spies, and from whence they carried the huge bunch of grapes (Num. 13:23-24; Num. 32:9; Deut. 1:24). In the district around Beersheba there are still miles of grape vines.
