Emerald: Heb. nophek
(Exodus 28:18; 39:11) i.e., the "glowing stone", probably the
carbuncle, a precious stone in the breastplate of the high priest. It
is mentioned
(Revelation 21:19) as one of the foundations of the New
Jerusalem. The name given to this stone in the New Testament Greek is
smaragdos, which means "live coal."
