of a sapphire stone: The Hebrew sappir, is without doubt the sapphire; which is a most beautiful precious stone of a fine blue colour, second only to the diamond in lustre, hardness, and value. The ancient oriental sapphire is supposed to have been the same as the lapis lazuli. It glitters with golden spots; and is of an azure or sky-blue colour, but rarely intermixed with purple. The ruby and topaz are considered of the same genus. Eze 1:26-27, Eze 10:1; Rev 4:3, Rev 21:19-23
