JACINTH
JACINTH properly a flower of a reddish blue or deep purple (hyacinth),
and hence a precious stone of that colour (Revelation 21=>20). It has been
supposed to designate the same stone as the ligure (Hebrews leshem)
mentioned in Exodus 28=>19 as the first stone of the third row in the high
priest’s breast-plate. In Revelation 9=>17 the word is simply descriptive of
colour.
