(1) rumination, the food which ruminating animals bring up to chew, the cud, Arabic جِرَّةُ, see the root גָּרַר No. 3. Used of a ruminating quadruped הֶעֱלָה גֵרָה Leviticus 11:3, seq.; Deuteronomy 14:6, Deuteronomy 14:7 and גָּרַר גֵּרָה Leviticus 11:7.
(2) a grain, a bean, so called from the idea of rolling, and the round form i.q. גַּרְגַּר, see the root No. 5; hence used of the smallest Hebrew weight and coin, a gerah, the twentieth part of a shekel, Exodus 30:13 Levit. 27:25 Numb. 3:47 18:16. [“LXX. ὄβολος, Vulg. obelus, either from the figure of a granule of lead (as Gr. ὄβολος, according to Aristotle, is from the figure of a spit or needle; Ch. מְעָא a little stone, obolus), or, because in weighing small things, the Hebrews used grains or kernels either of pepper or barley (compare English barleycorn), or perhaps the seeds of the carob tree.” Ges. add.] For it is very probable that the Hebrews, like the Greeks and Romans, used the seeds or beans of the carob tree [Ceratonia siliqua, Linn.], just as the moderns sometimes use barleycorns or peppercorns. [“But it must be remembered that the Mosaic gerah, which Isa 13:1-227/10 Paris grains, is equal to 4 or 5 beans of the carob, and, according to the Rabbins, to 16 grains of barley. Of a like origin are Arab. حَبَّةُ grain, berry, and خَرُوبَةُ carob bean; Persic داذق (δακνάκη) = داذك, داذه all of which refer also to small weights.” Ges. add.]
