¹²  You shall put the two stones on the shoulder-pieces of the ephod, to be stones of memorial for the children of Israel: and Aaron shall bear their names before Yahweh on his two shoulders for a memorial.

¹³  You shall make settings of gold,

¹⁴  and two chains of pure gold; you make them like cords shall, of braided work: and you shall put the braided chains on the settings.

¹⁵  'You shall make a breastplate of judgment, the work of the skillful workman; like the work of the ephod you shall make it; of gold, of blue, and purple, and scarlet, and fine twined linen, shall you make it.
