Thematic Bible: In the breastplate and ephod

And thou shalt take two onyx stones and engrave on them the names of the sons of Israel: Six of their names on one stone and the other six names of the rest on the other stone, according to their birth. With the work of an engraver in stone, like the engravings of a seal, shalt thou engrave those two stones with the names of the sons of Israel; thou shalt make them to be set in settings of gold. read more.
And thou shalt put the two stones upon the shoulders of the ephod for stones of memorial unto the sons of Israel, and Aaron shall bear their names before the LORD upon his two shoulders for a memorial. And thou shalt make the settings of gold and two small chains of pure gold; of wreathen work shalt thou make them and fasten the wreathen chains to the settings. And in the same manner thou shalt make the pectoral of judgment with cunning work; after the work of the ephod thou shalt make it, of gold, blue, purple, scarlet, and of fine twined linen. It shall be square and double; a span shall be the length thereof, and a span shall be the breadth thereof. And thou shalt fill it with four rows of stones; The order shall be a ruby, an emerald, and a chrysolite; this shall be the first order. And the second order shall be a carbuncle, a sapphire, and a diamond. And the third order, a topaz, a turquoise, and an amethyst. And the fourth row a tarshish (or beryl) and an onyx and a jasper; they shall be set in gold in their inclosings. And those stones shall be in agreement with the names of the sons of Israel, twelve, in agreement with their names; each one in agreement with his name like the engravings of a seal; they shall be according to the twelve tribes.

And they wrought onyx stones inclosed in settings of gold, graven, as seals are graven, with the names of the sons of Israel. And he put them on the shoulders of the ephod that they should be stones for a memorial to the sons of Israel, as the LORD had commanded Moses. He also made the pectoral of cunning work, like the work of the ephod of gold, blue, purple, scarlet, and fine twined linen. read more.
It was square; they made the pectoral double; a span was the length thereof and a span the breadth thereof, being doubled. And they set in it four orders of stones. The order was a ruby, an emerald, and a chrysolite: this was the first order. The second order, a carbuncle, a sapphire, and a diamond. The third order, a topaz, a turquoise, and an amethyst. And the fourth order, a tarshish (or beryl), an onyx, and a jasper; they were set and inclosed in their settings of gold. The stones were in agreement with the names of the sons of Israel, twelve, in agreement with their names, like the engravings of a seal, each one in agreement with his name, according to the twelve tribes.
