And they came unto the brook of Eshcol, and cut down from thence a branch with one cluster of grapes, and they bare it between two upon a staff; and they brought of the pomegranates, and of the figs. They bare it between two upon a staff - It would be very easy to produce a great number of witnesses to prove that grapes in the promised land, and indeed in various other hot countries, grow to a prodigious size. By Calmet, Scheuchzer, and Harmer, this subject has been exhausted, and to these I may refer the reader. Pliny mentions bunches of grapes in Africa each of which was larger than an infant. Radzvil saw at Rhodes bunches of grapes three quarters of an ell in length, each grape as large as a plum. Dandini saw grapes of this size at Mount Libanus; and Paul Lucas mentions some bunches which he saw at Damascus that weighed above forty-five pounds. From the most authentic accounts the Egyptian grape is very small, and this being the only one with which the Israelites were acquainted, the great size of the grapes of Hebron would appear still more extraordinary. I myself once cut down a bunch of grapes nearly twenty pounds in weight. Those who live in cold climates can scarcely have any conception to what perfection both grapes and other fruits grow in climates that are warm, and where the soil is suitable to them.
From what is mentioned Numbers 23:20, Now the time was the time of the first-ripe grapes, it is very probable that the spies received their orders about the beginning of August, and returned about the middle of September, as in those countries grapes, pomegranates, and figs, are ripe about this time; see Harmer, vol. i., p. 108-110. At Sheeraz, in Persia, I find from a MS. journal, that the small white grape, askerie, came into season August 6; and pomegranates September 6; and the large red grape, sahibi, September 10.
The spies' carrying the bunch of grapes on a staff between two men was probably not rendered necessary by the size of the bunch or cluster; but to preserve it from being bruised, that the Israelites might have a fair specimen of the fruit As Joshua and Caleb were the only persons who gave a favorable account of the land, it is most likely that they were the persons who had gathered these fruits, and who brought them to the Israelitish camp. And it is likely they were gathered as short a time as possible before their return, that they might not be injured by the length of the time they had been separated from their respective trees.
