Concerning the meaning of the Hebrew words translated "rubies" there is much difference of opinion. ( Job 28:18 ) see also Prov 3:15; 8:11; 31:10 Some suppose "coral" to be in tended; others "pearl," supposing that the original word signifies merely "bright in color," or "color of a reddish tinge." (The real ruby is a red sapphire, next in value to the diamond. The finest rubies are brought chiefly from Ceylon and Burmah.)
