Exodus 28:14

¹²  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.

¹³  And thou shalt make ouches of gold;

¹⁴  And two chains of pure gold at the ends; of wreathed work shalt thou make them, and fasten the wreathed chains to the ouches.

¹⁵  And thou shalt make the breastplate of judgment with cunning work; after the work of the ephod thou shalt make it; of gold, of blue, and of purple, and of scarlet, and of fine twined linen, shalt thou make it.

¹⁶  Foursquare it shall be being doubled; a span shall be the length thereof, and a span shall be the breadth thereof.
