Grapes of Eshkol
The grapes of Eshkol were so large that one cluster required a pole to be used to carry it. This may be a clue to genetically engineered/modified food that the giants of old were eating. Here is what the bible passages says:
When they reached the Valley of Eshkol, they cut off a branch bearing a single cluster of grapes. Two of them carried it on a pole between them, along with some pomegranates and figs. – Numbers 13:23
One cluster of normal grapes would fit in one’s hand.
