Viewing verse 10 of Exodus 39 (with context)
Read Full Chapter And he put them on the shoulders of the ephod, that they should be stones for a memorial to the children of Israel; as the LORD commanded Moses.
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.
It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being doubled.
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.
And the second row, an emerald, a sapphire, and a diamond.
And the third row, a ligure, an agate, and an amethyst.
And the fourth row, a beryl, an onyx, and a jasper: they were inclosed in ouches of gold in their inclosings.
