Heb. pitdah ( Ezekiel 28:13 ; Revelation 21:20 ), a golden yellow or "green" stone brought from Cush or Ethiopia ( Job 28:19 ). It was the second stone in the first row in the breastplate of the high priest, and had the name of Simeon inscribed on it ( Exodus 28:17 ). It is probably the chrysolite of the moderns.
