A gerah Hebrew "גרה" is an ancient Hebrew unit of weight and currency, equivalent to one-twentieth of a shekel, a shekel being 180 barleycorns or 60 carob divided by 20 = 3 carob. This is 0.568 grams. A gerah is in Aramaic a ma'ah "מעה" (Mishnah Hebrew ''pl''. ma'ot "מעות" which means "coins"). It was originally a fifth of a Denarius/zuz, as seen in Exodus ("20 gerah is a shekel"), then became a sixth of a denar/Zuz, such as the Yehud coins which came in two denominations, approximately .58 gram as a ''ma'ah'' and approximately .29 gram as a half ''ma'ah'' (''chatzi ma'ah''), and (.58 X 6 = 3.48) which is about the weight of a Zuz/Denarius based on a 14 gram Shekel. The Jerusalem Talmud Shekalim, in the Mishnah, debates if a ''kalbon'', which was added when annually giving a half shekel to the Temple, was a ''"ma'ah"'' or a ''"chatzi ma'ah"'' (half ma'ah). ==See also== *Biblical and Talmudic units of measurement *List of historical currencies *Yehud coinage *Zuz *Shekel 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gerah」の詳細全文を読む スポンサード リンク
