The place was called the Valley of Eshcol, because of the cluster of grapes which the children of Israel cut down from there.
All Commentaries on Numbers 13:24 Go To Numbers 13
Clement Of Alexandria
AD 215
Later on, a sacred vine put forth a cluster of grapes that was prophetic. To those who had been led by the Educator to a place of rest after their wanderings it was a sign, for the great cluster of grapes is the Word crushed on our account. The Word desired that the “blood of the grape” be mixed with water as a symbol that his own blood is an integral element in salvation. .
