Exodus 39:8-10

King James Version

⁸ And he made the breastplate of cunning work, like the work of the ephod; of gold, blue, and purple, and scarlet, and fine twined linen.

⁹ It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being doubled.

¹⁰ And they set in it four rows of stones: the first row was a sardius, a topaz, and a carbuncle: this was the first row.
