Exodus 28:4 "These are the garments which they shall make: a breastpiece and an ephod and a robe and a tunic of checkered work, a turban and a sash, and they shall make holy garments for Aaron your brother and his sons, that he may minister as priest to Me.

Exodus 28:6 "They shall also make the ephod of gold, of blue and purple and scarlet material and fine twisted linen, the work of the skillful workman.

Exodus 28:15 "You shall make a breastpiece of judgment, the work of a skillful workman; like the work of the ephod you shall make it: of gold, of blue and purple and scarlet material and fine twisted linen you shall make it. (NASB ©1995)
