Clement of Alexandria, on Num 13:24

“And going forward as far as the torrent of the cluster of grapes, they cut off a branch with its cluster of grapes, which two men carried upon a lever. They took also of the pomegranates and of the figs of that place:”

“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.”
