Exodus 28:5 (KJV)

And take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.

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

It shall have the two shoulderpieces thereof joined at the two edges thereof; and so it shall be joined together.

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.
