16 wheat grains. Nothing is more common than a change in the value of a natural weight unit, when in the course of time its real origin has been forgotten, and it has been adjusted to meet the requirements of newer systems. Thus the value of the Greek _thermos_ and its Roman equivalent the _lupin_ both suffered in later days, and were regarded as only equal to 6 wheat grains instead of the original 8 owing to a like confusion between wheat grains and barleycorns. Finally there is a further reason why the authors of the Septuagint Version would translate _gerah_ by _obolos_. Writing at Alexandria under Ptolemaic rule, at a time when the Ptolemaic silver stater of 220 grains contained exactly 20 obols of the Attic or ordinary Greek standard of 11 grains, they would all the more readily adopt a rendering, which harmonized so well with the monetary system of their own day; at the same time the Greek habit of dividing all staters into 12 _obols_, no matter on what standard the stater was struck, naturally would incline them all the more to regard the _gerah_ not as an actual weight, but simply as the twentieth of the shekel, be the shekel what it might. The Hebrew gold standard accordingly consisted of a shekel of 130 grains, subdivided into 2 _bekahs_ or _halves_; each of which in turn contained 10 _gerahs_ or lupins: 100 such shekels made a maneh, and according to Josephus[338] 100 manehs made a _kikkar_ or talent. It would thus appear that, just as in the time of Solomon the heavy mina had been introduced which was equal to 100 shekels of the Sanctuary, so the Hebrews carried out consistently this principle by making 100 minae go to the talent. It is however most probable that before that time they had employed a maneh of their own of 50 light shekels, for we have seen above that the talent of silver mentioned in Exodus consisted of only 3000 shekels, just as in all the other gold and silver systems of Asia Minor and Greece: and since we have proved that the silver shekel of the Sanctuary was the ordinary light shekel of 130 grains, it is evident that the silver talent is not made up of 3000 double shekels, but is really nothing more than the sixty-fold of a mina which contained 50 shekels of the ox-unit standard. If gold was weighed at all by any higher standard than the shekel, it is almost certain that it must have been weighed by this mina and talent[339]. However, by the time of the monarchy it is most probable that the double or heavy mina had been introduced for silver as well as for gold. In fact the probabilities are that it was applied for the weighing of silver before that of gold. Thus when Naaman the leper set out to go to the Hebrew prophet, “he took with him ten talents of silver, and six thousand [pieces] of gold, and ten changes of raiment[340].” Here the 6000 gold pieces are perhaps the 6000 light shekels which would make a talent of the heavy Assyrian standard after the ordinary
