Exodus 28:7 (KJV)

And thou shalt make holy garments for Aaron thy brother for glory and for beauty.

And thou shalt speak unto all that are wise hearted, whom I have filled with the spirit of wisdom, that they may make Aaron's garments to consecrate him, that he may minister unto me in the priest's office.

And these are the garments which they shall make; a breastplate, and an ephod, and a robe, and a broidered coat, a mitre, and a girdle: and they shall make holy garments for Aaron thy brother, and his sons, that he may minister unto me in the priest's office.

And they shall take gold, and blue, and purple, and scarlet, and fine linen.

And they shall make the ephod of gold, of blue, and of purple, of scarlet, and fine twined linen, with cunning work.

And the curious girdle of the ephod, which is upon it, shall be of the same, according to the work thereof; even of gold, of blue, and purple, and scarlet, and fine twined linen.

And thou shalt take two onyx stones, and grave on them the names of the children 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 signet, shalt thou engrave the two stones with the names of the children of Israel: thou shalt make them to be set in ouches of gold.

And thou shalt put the two stones upon the shoulders of the ephod for stones of memorial unto the children of Israel: and Aaron shall bear their names before the LORD upon his two shoulders for a memorial.
