Numbers 13:22-24

22 And they ascended by the south, and came to Hebron; where Ahiman, Sheshai, and Talmai, the children of Anak, were. (Now Hebron was built seven years before Zoan in Egypt.)

23 And they came to the brook of Eshcol, and cut down from there a branch with one cluster of grapes, and they bore it between two on a staff; and they brought of the pomegranates, and of the figs.

24 The place was called the brook Eshcol, because of the cluster of grapes which the children of Israel cut down from there.
