Exodus 28:17  (King James Version)
And thou shalt set in it settings of stones, even four rows of stones: the first row shall be a sardius, a topaz, and a carbuncle: this shall be the first row.

thou shalt
Exodus 28:9 Exodus 28:11 ; 39:10-21 Malachi 3:17

set in it settings of stones
Hebrew fill in its fillings of
the first row.
Ezekiel 28:13 ; Revelation 21:19-21

a sardius, or, ruby
The Hebrew {odem,} from {adam,} to be red, ruddy, seems to denote the ruby; as {adam} does in Persian a beautiful gem, of a fine deep red colour, with a mixture of purple. Job 28:18 ; Proverbs 3:15 ; 8:11 20:15 31:10 Lamentations 4:7

a topaz
{Pitdah,} is constantly rendered by the LXX. [topazion,] and Vulgate, {topazius,} with which agrees Josephus. The topaz is a precious stone, of a pale, dead green, with a mixture of yellow, sometimes of a fine yellow; and hence called chrysolyte by the moderns, from its gold colour.
Job 28:19 ; Revelation 21:20

a carbuncle
{Bareketh,} from {barak,} to lighten, glitter, a very elegant gem, of a deep red colour, with a mixture of scarlet.
Isaiah 54:11 Isaiah 54:12
